With Arfcom member Amphibian demonstrating the Griffin gas block that owes its design to the MICROMOA Govnah gas block. MicroMoa sold us the patents a few years back and we finally were able to bring the product to market. The podcast with Robert on the history and development of the block will be live in a few hours.

Quoted: Thanks- I regrettably am pretty late to the party on adjustable gas. I do think it really brings a lot of advantages to a rifle build used with a suppressor. Quoted: Quoted: Very cool, Green. I look forward to picking one up and trying it out! Thanks- I regrettably am pretty late to the party on adjustable gas. I do think it really brings a lot of advantages to a rifle build used with a suppressor. I held off for years too. Trying everything but actually dealing with the gas. Buffers, springs, adjustable BCGs, every gas busting charging handle imaginable. Even had a one of those corkscrew shaped gas tubes lol Finally going to AGBs and BRTs(in FSB guns) made everything so much easier. |
| I posted in the other thread as well, but I want to pick one up for my 12" 6 ARC build with Polonium. Already has a gen 2 SN-ACH. Thinking I'll probably need to do a drill your own, but I am interested in the hole sizes on the conventional 5.56 carbine as well. |

Quoted: Very neat, how much gas leakage is there between the plate and the body though? Seems like this design could have a large amount. |

Quoted: Very neat, how much gas leakage is there between the plate and the body though? Seems like this design could have a large amount. I shot it with a handguard and didn’t even notice it. Amphibian mentioned he could beer can grip the rail and notice it but was impressed by how low it was. The tolerance is held to around .0015” on the disk and the .108 counterbore hole is small. We tested it to .0025 simulating high and low limit and .0005” extra and I didn’t notice anything. The gas check grooves are interrupting gas flow and redirecting it. Quoted: @Green0 What size holes are in the Carbine gas conventional suppressor plate? Trying to decide if I want the 4 hole DIY plate of just get the pre-drilled one. Thats a good question. I asked the guys to publish a photo of current sizes or excel sheet. I guess that didn’t happen yet. I’ll try to get that done next week. I think the carbine conventional sizes are .048” and .052” with the two .096” normal holes that rely on the barrel port from the manufacturer. |

I'll wait to order until next week sometime. I'm confused on the descriptions of the plates. So all the options other than the drill your own only have two holes or four holes? ETA: forgot to say thanks for answering questions on a weekend! I visited the showroom a couple weeks ago and you have some nice stuff in there! Very interesting visit. |

Every plate has 4 holes- on each side is one suppressed port and one unsuppressed port in the factory configured plates- the idea being you can find which side your can likes, and leave it on that side, just moving to N or S. One side of the block has two slots on the diameter for identification of one side vs the other. So it you want the side with the slots on the side, you could paint mark a vertical line on the rail's right side, reminder you use the slotted side. If you used a LBP plate it could be I L marked indicating slotted side and LBP plate so you know which cans it is set up for in the instance of 10 guns or something to keep straight. No marks would mean conventional plate on the smooth side right, so you would know how each rifle was setup. 2 drill your own plates have 2@ a larger pass through size for normal and 2 at .034" for pre-drilled holes for drill your own applications. One drill your own has all ports at .034" for each size to be drilled to the customers spec. All the holes have .108" diameter counterbores at 118 degrees drilled with a 1/8" drill- we figured this reduces potential to carbon bind, and also creates a low erosion angle into the actual port as well as a pilot drill angle for the pre-drill applications. A customer for example could drill one hole normal pass through at .093 or .096, and take the larger LBP setting and put it into the normal position on the inverse side of the plate/disc, and have the two conventional sizes, allowing them to use conventional and LBP cans interchangeably and also have a normal setting for unsuppressed with a 4@ .034 drill your own plate and their chosen drill sizes. This is the information that should be posted on the pages. Glad you were able to visit.  This is a very bad picture for showing this, and there are much better images in the manual that comes with the product that also needs to be uploaded to the pages. You can see two notches at the 12 o-clock which are gas check grooves that were cut up through the outside diameter, and are very visible on the opposite side of the regulator plate. The regulator plate images could be improved here. (like having one of the other side and opposite rotation for example). This image is the top so the .108 118degree counterbores are not visible, and the gas check grooves are not visible. On my screen this is like 5 times actual size, so the finish looks rough but it is pretty smooth. It is cut at .0028" revolution feed so it is pretty smooth.

Quoted: Sorry, I am still a little confused. Would it be possible to get a plate that has 1 large setting that is basically the barrels port size, a conventional suppressor hole, and LBP hole and maybe a something in between the two suppressed settings? If you bought the drill your own with the 4 .0334" holes, you could drill one .093 (a common bit [3/32] normal pass through- this one does not have to match a barrel port size because the barrel itself does that), one conventional, one intermediate, and a third [the final position wherever you wanted that setting on the other side] LBP of the larger hole size and that would be that product. We aren't making one that way right now. In a vise pinched snug (not crazy tight) between the two large U shaped notches with the gas check slots and .108 counterbores facing up, a hand drill and a new HSS bit will drill a hole in about 40 seconds using oil for coolant and low RPM to prevent the bit from getting hot. I drilled a bunch during testing using latrobe black oxide hss number drills from amazon from one hole size to another that way and it was pretty easy work with no machines involved. I didn't ever fail to drill a hole, I never killed a bit. I used light pressure almost just the weight of the drill only and low RPM and just made sure chips were being made. The only obvious way to kill the bit would be pushing hard or running the drill as fast as it could go, because heat and over-feed is how 17-4 could hurt a fresh HSS bit. Right now the idea is a person knows they have a conventional can for example, and mid gas, and they get the block with that plate, and they use the two suppressed settings, decide which they like better, leave the block on that side of the plate, and select suppressed or normal depending on whether they are running the can. I do understand how your method would make more sense for people interchanging LBP and conventional cans often, who had less interest in having the K.I.S.S. concept simple method with 2 settings, and more interest in having like a one size fits all baseball cap. Maybe if we find out we're selling a lot of these and fielding that often, we can make that a product at some point. Latrobe # drill set 118 degree black oxide (only about half this set is relevant as the rest is over .100" size) Conversely, Mcmaster carr sells metric HSS black oxide coated bits for ~$3.2 per drill, so 4 bits is like $13.00 if you know what sizes you want. The ideal complete set for gas ports would be like .9mm through .2mm in increments of .1mm as .004 is pretty reasonable as an increment for these changes. That would only be like 11 bits for $32 or so. We were working with CNC bits for like $14 from NACHI and they make them in increments of like .001" of an inch, so we could choose whatever we wanted and they had 3mm or 1/8" shanks which is also nice because some drill chucks don't close down to smaller than around .060" and that kept the collet in the CNC machine from needing to be swapped for every drill change. |

Quoted: I'll have to check the videos out when I get home. Are they only for .750" barrels or anything for pencil .625ish ones too? The first model is 3/4". I don't know if we will have a 5/8" model or not. I think we sell very few 5/8" blocks. So that diameter is obviously a minority diameter in the current market. That doesn't mean it is a bad idea to support it, it just means it probably makes more sense when we have had some sales of the 3/4" blocks we are launching now. I think we have a plan to offer a version for DPMS high rail (DPMS/KAC style) at some point, and that will use the bent rifle length tube because it has a pretty high profile and making the part super high is kind of a lot of machining stock to buy and remove. Current production is from bar stock. |

Quoted: What's point of an adjustable gas block that you have to "tune" with specific load? Seems gimmicky My AR's pretty well have dedicated suppressors. I have put BRT has tubes in them that choke things down but still allow function without the can. This makes my guns gassy with rapid fire or large strings when suppressed. This gas block will allow me to have 2 custom settings. Suppressed and unsuppressed (likely never use) without requiring me to change buffers, etc. |

Quoted: What's point of an adjustable gas block that you have to "tune" with specific load? Seems gimmicky Quoted: What's point of an adjustable gas block that you have to "tune" with specific load? Seems gimmicky We already sized the ports to the gas system length and suppressor class for our barrels with PMC TAP 55 grain ammo (commercial so the commercial ammo will work as well as nato). The point is that no modern respected military on planet earth would ever adopt a rifle with an infinitely adjustable gas system. But the HK416 and the FN SCAR do have normal and suppressed gas settings and have been issued. All the people with experience want either no adjustment or 2 or 3 simple settings, and typically if there are 3, one is adverse for operation when heavily fouled and poorly lubricated. So only one setting can make the gun not run if the suppressor isn't attached, and that's what these militaries are concerned with, and that is solved by one position change of the system. In the infinite systems the soldier can't call a time out while he finds the tool, and finds the "tune" that lets his gun operate. He would just potentially get killed or be useless to his element at that point. That's because there is a difference between a total hobby item for consumers and something simple enough to work and be dependable for duty use. Quoted: Sounds amazing to me! Some adjustable gas blocks don't have fine enough adjustment. 1 click can go from still too gassy to single shot. A complete drill your own will let me have an unsuppressed setting that I find is smooth and reliable (which is often smaller than most manufacturers put in a barrel) as well as a choked down setting that I am happy with. My AR's pretty well have dedicated suppressors. I have put BRT has tubes in them that choke things down but still allow function without the can. This makes my guns gassy with rapid fire or large strings when suppressed. This gas block will allow me to have 2 custom settings. Suppressed and unsuppressed (likely never use) without requiring me to change buffers, etc. If you have developed port sizes from something like the EZ tune, you could certainly integrate those settings in a plate and that should work. You technically have 4 ports here, so two unsuppressed and 2 suppressed settings, or 1 unsuppressed and 3 suppressed, or you could mirror the 2 settings, so you have just 2 and a replacement set of new ports on tap- however you want to configure it. It can be as simple as not needing to pay attention to which side of the plate you are on and just putting the notch on the right side forward for suppressed and rearward for normal, or as complicated as 4 different settings. |

Quoted: Thanks for the clarification on the plates. It makes sense now. You're basically getting two sets per plate it seems. I'll be ordering one along with the straight gas tube. These should be perfect for my intended use. Thanks for the new product! Yes the idea there was give people a little room for the system to operate with different cans. The suppressed holes of the two sides are .004 apart on conventional plates and .008 apart on low backpressure plates. Obviously if a plate doesn’t run because a can is for example really short and louder and bridging the gap between high flow and conventional, a person could obviously change the size on the plate, so worst case the provided plates smaller gasports can be resized to larger ports but the intent of two sides was to reduce the incidence of that. In our testing most of our size changes from our estimates which were based on Micro moa work, were about .004” so they were minor. The LBP stuff of course was uncharted territory. To spin the plate 180 to the other side and its settings takes a conscious effort using the bullet tip in the detent notches, and often requires manipulation of the plate/disk from both sides of the rail, so it is not likely to happen by accident. That plays to our intent to make it simple and 2 used positions after initial orientation and settup. In suppressor design it is very difficult to get a suppressor into the range of low cyclic increase and basically requires some gas to be routed by most of the baffles in the can without restriction. So for example if I put 8 large holes on the periphery of each of 6 baffles in a can, and do not vent the cap, i can pick up sound by about 6-7DB drop cyclic increase to around 11% but that doesn’t reach 5-6%, because the venting of gas is still baffled despite such high flow. So the defining characteristic of lbp cans is largely unbaffled flow bypass and that is pretty easily identifiable. In other words most suppressors will fall into one of these two classes. Surefire demonstrated and patented a way to do it without resorting to 100% printing, but they didn’t do it with zero printing. In other words printing is fairly important to manufacture geometry capable of obtaining that functionality, if that is even desired. I personally lean toward a hybrid of higher than traditional flow with better than normal sound in conjunction with adjustable gas as perhaps where the sweet spot might be, but only time will tell how the development of technology will pan out. |

I asked the MicroMOA guy this years ago when I got my Govnah’s from him, he basically chewed me out for some reason for even asking haha. Love my Govnahs though, although they don’t function on my CAT suppressors due to the reduced blowback. (The rifle is undergassed on the suppressed setting). Works fine on the unsuppressed setting. |
| I added the function macro video and digital install manual link up top because a lot of people wanted to better understand what we were offering. The part looks a little rough because it is black oxide finished, but that's because Nitride often changes dimensions on a small level, and the gas tube and block tolerances are like .0005" tight, so there isn't room for warpage. |
| My first order got cancelled for "not choosing" a plate. I did. Placed a second order and just missed a call from you guys stating there was an issue and asking what plate I wanted. I tried calling back but will probably just wait for the email he said he'd send. |

I asked the team to investigate it so we can try to ascertain what the exact problem is and get it resolved hopefully tomorrow. I know I kind of rushed the launch as for me this was a two year process whereas for some of the other people involved it was one year or 5 months, 3 months or in some cases 3 weeks or even 6 days, depending on where in the organizational structure they are. For the people such as fulfillment where their knowledge of the project perhaps began 6 days ago, it was really “quick”. I was just told the first 45 orders were not properly put together and someone may have decided to delete them. I apologize for that. It isn’t our intention to waste anyone’s time. I told the operations manager that I would rather we had worked the orders on the back end manually as we’re not here to give people a bad experience. The new website was required to work with the FFL compliance network sales product for firearms. The thing that gives a person the ability to select an ffl for a firearm sale, used a plugin that wasn’t supported by big commerce. The new website has a complicated and stupid problem of a very particular product settup theory to keep a loophole closed of a inclusion product being able to be added multiple times for free- that also kills the order. Like a rifle with 47 sets of tan handguard panels. To make a rifle a sku with 4 colors of handguard panels, and 27 muzzle device options blows one rifle into like 108 skus. It becomes a nightmare so the very particular workaround is something I don’t even understand because it is too complicated to be explained to me in a way I can understand it. Basically Netsuite is a $60,000 initial cost or higher software that takes people forever to master at the cost of hundreds of thousands of dollars, and it has to talk to the website through plugins and connectors also. I’m not impressed with netsuite. We’ve had it like 4 years now. |

I don't envy you (your guys) having to handle multiple custom option SKUs. :-/ Two related questions have come to mind. Will this be an option on barrels (or uppers) or will it have to be ordered separately? Going from 72 to 144 variants for each full upper sounds like a royal pain, but going 2 to 3 options on a plan barrel appears simpler. Can a Roll Your Own adjustment disk come with a countersink but no hole? I can see one of us oddballs wanting an occasional single shot for max suppression. |

We are putting the drop down options into firearms and uppers today. There is some way to do this without it blowing up to insane amounts of inventory controlled skus, but it is complicated (hence the mistake with original configuration), I was told they resolved the problems yesterday on the block and plate pages, and this morning I was told that the work to get the drop down options into firearms and uppers had begun. To buy one with a barrel, would essentially be the same as dropping the block/plate, and the barrel in the cart at the same time. We weren't planning to do the plates with no pre-drilled holes as we feel that just increases the odds of drill breakage with the customer during drilling their own hole. What Amphibian said works- between settings it is shut off. That's easy to do, and I really don't think it is very novel so people will likely do that once or twice and say it's too much pain in the ass to extract a case from an AR15 without any kinetic energy and motion in the BCG, so it likely won't be something people do often. |

It’s probably in process, along with the $45 option add on uppers and rifles. |

I got too excited building my Craddock Precision 6ARC upper so I forgot to check port size I’m always changing things around; I’ll probably end up with a GA block. Probably need some nonstandard sizes running 6ARC with intermediate gas on a 16” barrel . Suppressor is a new model Explorr .30, and eventually I’d like an Optimus 6 on it |

Quoted: Maybe I should jave asked before ordering. Do these gas blocks have any fitment issues with any rails? Mine will be going under a SLR rail. Quoted: Maybe I should jave asked before ordering. Do these gas blocks have any fitment issues with any rails? Mine will be going under a SLR rail. No known fitment issues. Everything has a pic rail up top for the most part, and that creates clearance for the block. Our rails are 1.375" ID which is typically the smallest ID and they work. (STD GI is approximately that diameter). One of the gas tubes Carbine length straight, was miss-packaged normal bent. If anyone got one of those, CS is in the process of sending a straight tube and return ship envelope for the bent tube. Sorry for the packaging label error.

I haven't gotten into any of the odd caliber stuff. Typically ammo prices are bad enough for standard calibers, without getting into 6 Arc, 223 Valkyre 6.5 grendal, 6.8SPC and others. The firearms industry does a lot of odd caliber stuff, and often it is a fad. It's up, it's down, and then at a point it can be damn hard to find ammunition at reasonable prices. Some of the decisions don't make a ton of sense. .300PRC and .300 norma both do a lot of stuff similar to what .300 Win Mag does too. The .300Win mag is more established and less expensive. |

Green0, after 2 days of messing around with orders getting screwed up by your system, I got my gas block order in the night of the 18th so you had it the 19th. I guess these gas blocks aren't shipping just yet? Ordinarily, your shipping is lightning fast, I place the order, got a confirmation and get the parts two days later. You make a lot of great stuff, but you're running way ahead of your supply chain. I'm still waiting for a titanium 1/2"-28 minimalist flash l hider I ordered, probably over a year ago, through a dealer and it looks like the Terra Brown snatch 15 charging handles are on eternal backorder as well. |

Quoted: Pretty cool but too late for me as I've already heavily invested in RS AGBs. Perhaps if l build another upper in the future. Good to see amphibians AGB original design brought back again with some nice improvements. I love the rifle speed gas blocks, I was going to go that way on a 12.5" upper I'm assembling, but an email ad for this Griffin gas block popped up. It took a few tries ordering it, Alexander and Hunter were very helpful. I hope it's worth the wait. I have four guns set up with the rifle speed gas blocks and they're amazing. I just want to wait a while to see if there are any long term problems with them. To me, they are unproven. It says on the RS website that you have to clean them every 700 rounds which isn't very easy, considering two of the four of my guns have the gas block under the rail. I just use a needle oiler to lubricate the pin and run it through the 1- 12 settings and so far I've had no issues. We should find out soon from people that have enough money to shoot a lot of rounds through Riflespeed equipped rifles. |

Quoted: Green0, after 2 days of messing around with orders getting screwed up by your system, I got my gas block order in the night of the 18th so you had it the 19th. I guess these gas blocks aren't shipping just yet? Ordinarily, your shipping is lightning fast, I place the order, got a confirmation and get the parts two days later. You make a lot of great stuff, but you're running way ahead of your supply chain. I'm still waiting for a titanium 1/2"-28 minimalist flash l hider I ordered, probably over a year ago, through a dealer and it looks like the Terra Brown snatch 15 charging handles are on eternal backorder as well.

Please shoot me your order number via DM so I can look into it. Remind me about the terra brown handle and I will see if I can find one if we have any at all perhaps like sequestered for rifle builds. I know that 5 axis machine had a zero clamp workholding system wear out so we ordered 3 new clamping pots for like $3000 from Hoffman Group last week- there is no rebuild kit even though a rebuild kit would work. We have a terrible set of software and plugin to the website, and there was some issue with that that caused 50 of the first orders to be deleted I believe. The product was reconfigured so that it worked properly rapidly thereafter. The titanium muzzle devices are showing in stock: https://griffinarmament.com/shop/taper-mount-minimalist-brake-titanium/ https://griffinarmament.com/shop/dual-lok-minimalist-brake-titanium/ I had told amphibian that we would launch on Friday, and I tried to keep my word and it was a little quick for the team struggling with the configuration of the product pages and ERP software page settup. They just showed me the first option add page on the website tonight. Visible at the bottom: https://griffinarmament.com/shop/mk2-patrol-14-5-223w-carbine-pinned-to-16/ That was something I said would happen in the posts earlier. One of the issues with hasty product launches, is that if I waited a week or two, it probably wouldn't be enough time either. So it's kind of like skydiving- eventually you just have to jump instead of planning for later. This week has been busy. Renishaw has been here training on us on some expensive new equipment since Tuesday and planned through Friday. It's always busy, and this week isn't an exception. Quoted: I ordered my gas block over the weekend and it shipped on Monday. Tracking says it will be here in MN tomorrow. Thanks for the report. |
| I ordered on the 13th (Saturday), it got cancelled first thing on the 16th. Placed the order again on the 16th, Griffin fixed their issue and confirmed my order on the 17th, and it shipped on the 19th. 2 days isn't bad. The problem is now USPS. It's supposed to be here tomorrow but it arrived in LA for whatever strange reason today. I'll hopefully get it Saturday or Monday. |

So the titanium flash hider in 1/2"-28 is out of stock, I don't care anymore, as I now have muzzle devices on everything I need one on, with a steel minimalist leftover. No need to check the order, I'm not asking for special treatment. It's just frustrating that as soon as your email popped up, I thought I would be the first on my block to have one and ordered one, and here we are. |
