The reduced reciprocating mass is a great benefit for keeping the barrel on target. My main plan is for my super lightweight build. Imagine this carrier coupled with a extremely lightweight barrel, magnesium upper and lower, Aimpoint T1, JP Silent Buffer and a BCM KMR13. This should push the rifle weight down to the low 5 pound range easily. My goal is to offer a 14.5" middy rifle on our new billet receivers, that's under 6lbs. Sweetness!! Any plans to have the uppers & lowers available as stripped units? |

Hey, there ya go. I drilled one of my gas blocks for a set screw and then drilled the set screw out in kind of the same way. Like a jet in a carbeurator. Quoted:

How about a drill your own low pro gas block? Baby Govnah I thought this was one hell of an idea. Hey, there ya go. I drilled one of my gas blocks for a set screw and then drilled the set screw out in kind of the same way. Like a jet in a carbeurator. I like that even better. If you drill too much, start again with a new screw. Or have several sizes made up in advance, and swap em out to find what size works rather quickly. |

Below are liniks to a new two part article that came out last week on our patented, tool less modular adjustable gas block: Part 1: http://www.recoilweb.com/micromoas-govnah-adjustable-gas-block-38489.html Part 2: http://www.recoilweb.com/micromoas-govnah-adjustable-gas-block-pt-2-of-2-38639.html ![]() You can see that the Govnah is based on actual port sizes from NO port to whatever you want to drill. In the event that your barrel is overgassed and you don't want to run suppressed, I personally would have 1 port match your barrel's gas port which would be your adverse position (for use when dirty or using weak ammo) and you would also use that to install/align the block for installation then work your way up like you would on the baby Govnah to a port size that locks your bolt back on the other port. Or go with a 3 position if you want a position for a suppressor as well. ![]() Plenty more info,pics and videos at my site: micromoa.com |

Of course you're working on something heavy too right?

I would imagine titanium would benifet a bolt more than carrier since titanium should be a stronger steel than C-158. As for the carrier, it would make it lighter which would increase cycling rate and decrease dwell time. One could just buy a semi steel carrier and lighter buffer if decreased dwell is what you're looking for. It's lighter, but not stronger than steel, a Ti bolt wouldn't last long. Pure Ti is too soft, alloy is too hard/brittle, and will not take the abuse like steel will, also, it will not take high heat, it has a low ignition point, high heat will set it off, it sparks up quickly, which can ignite it, a Ti muzzle device would ignite with a shot or two, the high heat and direct flame would light it off. I have dealt with almost 30 Ti fires, all of them due to minor sparking, or high heat exposure. High heat will also cause the Ti to draw in more oxygen, and become even harder/more brittle. I work in the Ti industry, and do prep alloys for melting. Ti flexes under certain forces, but the locking lugs will not take the beating when the bolt goes into battery, and it is expensive material to use. There is also a reason Spikes carriers have a steel liner...keep the steel bolt from tearing up the Ti. |

I like the idea of the steel liner, BUT neither my Progressive Machine & Tool Titanium carrier nor any of my THREE DECADES OLD aluminum carriers have worn out the bore in the carrier. I also agree Titanium is not well suited as a AR-15 Bolt material, that is why I'm glad Spike's is offering a S7 bolt |

I was looking for something like this for my lightweight build, but I am going SBR, so I might pull by muzzle device into the 10" BCM mag handguard. If I do I need something linear and light weight. Looking at the Simple Threaded Device at 2.2oz for that, unless I can find a better option. This unit makes me rethink that. Have to look into this.

I personally think that the main problem with an aluminum carrier is going to be the cam pin slot and the hammer ramp on the bottom. I think it would destroy itself over time, I don't think they will hold up for very long even with hard anodized finish. Even 7075 aluminum is just to soft. It would basically be a throw away, even with the tool steel sleeve in it. I don't know if the carrier face would hold up either beating into the 8620 tool steel barrel extension over and over again. Honestly in this application I think aluminum is a very bad idea. They would be even lighter than Ti and much cheaper to produce though. Quoted:

As long as it was clear in the literature that it was to be used in semi only and is a disposable item, I bet you could sell at least one production run of them. I am sure you would torture test them in your Compressor to get a feel for how long they will last. And not that they are great hammers, but a poly hammer would eliminate the chattering damage. Could a steel sleeve in the front be cut for the cam track? |

Interested in the weight and expected price point for the Ti castle nut. I'm getting a Spikes or the V7 Weaponry version for my LW build. Which one I purchase will be decided on those two factors (weight/cost).
This is an exciting time for the LW craving crowd and it looks like some real R&D getting done out there for LW parts. |

Considering that ALUMINUM carriers are still around after three decades of being out of production and being used. I would think that Titanium will last a hell of a lot longer AND, Tom's S7 Bolt should outlast every damn 158C or every 9310 bolt by MANY times the round count! |

Our new 6AL4V Titanium carrier has some awesome features which we are in the process of getting a patent on. So I can't say much right now, but with this new carrier you don't need to use an adjustable gas system, heavier buffer, or a heavier buffer spring, even with the reduced weight. Just drop it in place and start shooting. Also our carrier has a Tool Steel sleeve inside the bore for added durability. It's done the same exact way that steel sleeves are put into Aluminum race engine blocks. They are also Hard Anodized Grey and infused with Teflon for wear resistance. Here's the prototypes (made for our shooting team) these don't have the patented features shown. :-) <a href="http://s135.photobucket.com/user/badazzar15/media/Intake/0E9F4D25-AFA1-44AB-BD38-78F7AC5239A6_zpsqhzw64p0.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/Intake/0E9F4D25-AFA1-44AB-BD38-78F7AC5239A6_zpsqhzw64p0.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/5F389912-9C1D-4C65-8B02-4CC676555BE4_zpsuyolvsyd.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/5F389912-9C1D-4C65-8B02-4CC676555BE4_zpsuyolvsyd.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/10CE2F10-5A53-4F6A-B109-FE05E8D60237_zpsyac19s6k.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/10CE2F10-5A53-4F6A-B109-FE05E8D60237_zpsyac19s6k.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/D38FC5F9-1A72-4322-9294-F91C97EC0CF5_zpsoqnl5iv0.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/D38FC5F9-1A72-4322-9294-F91C97EC0CF5_zpsoqnl5iv0.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/0309EDBB-BB2B-4314-800B-7F148F6FE4F2_zps3tgfbzwb.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/0309EDBB-BB2B-4314-800B-7F148F6FE4F2_zps3tgfbzwb.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/204004F8-C9A2-4B05-841D-A7A9A2074CAE_zpslgfrhsxu.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/204004F8-C9A2-4B05-841D-A7A9A2074CAE_zpslgfrhsxu.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/B6ACC48D-A976-4107-9199-D2F72DE5DD86_zpsbc46scvr.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/B6ACC48D-A976-4107-9199-D2F72DE5DD86_zpsbc46scvr.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/1FBD3C20-6683-4D9E-AF61-0C57EF24FE96_zps80wi9koo.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/1FBD3C20-6683-4D9E-AF61-0C57EF24FE96_zps80wi9koo.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/AB992B41-9473-4C6F-812E-E430D3EBB2FD_zpsrtjhutig.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/AB992B41-9473-4C6F-812E-E430D3EBB2FD_zpsrtjhutig.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/CC3C72BB-1216-4AD3-BA7A-635F10AEB780_zpsukgvtiii.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/CC3C72BB-1216-4AD3-BA7A-635F10AEB780_zpsukgvtiii.jpg</a> <a href="http://s135.photobucket.com/user/badazzar15/media/9178E091-C84B-47E8-B8A0-5409FBB4EC3F_zpstxgcsdhn.jpg.html" target="_blank">http://i135.photobucket.com/albums/q160/badazzar15/9178E091-C84B-47E8-B8A0-5409FBB4EC3F_zpstxgcsdhn.jpg</a> Why all the holes?

I thought that a lighter weight BCG could result in "carrier bounce" from the slight elasticity of the BCG slamming forward and bouncing back out of battery partially, let me see if I can find the video. dang it cant Lighter weight carriers were meant to be used with reduced gas in gamer guns. Less gas to compensate for this and to prevent over accelerating the carrier. |
