This weekend I took my AR carbine with Govnah adjustable gas block to the range for the first time and was impressed. Simply the Govnah adjustable gas block reduced felt recoil, while the system ran cooler and remained cleaner. As an added benefit the Govnah provides a high gear option, which can be used when the system eventually gets dirty and starts malfunctioning.
The block reduced the felt recoil and allowed for accurate follow-up shots and rapid-fire strings. The carbine shot almost as smooth as my A2 H-Bar Rifle. The block accomplished this by providing a low setting, which regulates the gas input to its optimum setting for a 16” carbine. From what I have read most manufacturers over-gas their systems so that a wide range of ammunition will work reliably in their barrels/guns. A symptom of over gassing is higher recoil impulse, which makes the carbine feel bouncy. The Govnah solved this problem in my carbine, it was very stable and follow up shots were on the money. I now love my carbine and am going to put a Govnah gas block on all of my ARs moving forward. Oh but it got even better. After shooting 120 rounds I inspected the bolt, carrier, inside the upper receiver, and breech. The carrier and receiver were clean and still had the light oil sheen I put on it before starting. The bolt and breach were much cleaner than what it would have been with the low profile gas block I had on it before. In the past after shooting 120 rounds there was always a noticeable amount of carbon build up which would require cleaning afterwards. This was not the case with the new gas block. There is one caveat; the Govnah that I purchased only had plates with port sizes for Suppressed and Un-Suppressed 16” Carbines. Since I don’t have a .556 suppressor yet I modified one of my plates so I could have a low and high gear. Based on what I read below the “Overdrive Demonstration (scroll to the bottom)” on MicroMOA site I bored out the Suppressed port to .0625 and the Unsuppressed port to .070. When I tested I shot all but 10 rounds in the low position. I fired my last 10 rounds in the high position, which significantly increased the recoil felt. Hopefully, I am never in a situation where my life depends on my Carbine but if it ever comes up it’s good to know I have high gear to keep the fight going longer. I took pictures of the install and inspection of the bolt that I am putting into a longer write up wich I will post later this week. |

Well since I don't have a .556 can as yet my heart is intact (thanks for caring your so sweat). My main issue was reducing the recoil in my carbine length AR which the Govnah solved. All the other benefits were just icing on the cake. |

Per the website, the coated gas port pieces are too difficult to drill to make the ports larger. How difficult was it to make the ports larger? I've been in contact with the company, saying that I would love to try it in my 300 BLK and even hinting I would send him the bullets he needs and is out of, but no luck. I thought about buying the gas block and drilling out the ports for my 300 BLK, but was stopped by the statement they would be too difficult to drill out. I use adjustable gas blocks on 2 of my 300 BLKs, using differing settings for subsonic and supersonic and want something that doesn't clog up and is easier to adjust. |

TaylorWSO here are some responses to your kind feedback: 1. "Bullshit you defeated physics now???" From my perspective this is simply an exercise in common sense, you put less hot gas and carbon in the impingement system then its probably going to run cooler and also cleaner over a longer period of time. Oh, and after dumping 4 mags it was much cleaner than it would have been with my old low pro gas block. 2. As for me being wrong on there being less recoil well I shot it a lot before and after installing the block and it is now much smoother and has significantly less recoil now after the block. That was the only modification that I did so it's likely the Govnah had something to do with it having less recoil felt. 3. As for me not knowing how suppressors work well I have cans on my subgun and pistols and am quite familiar with the back pressures they produce and how the baffle stacks work. I would imagine the principals are the same in with a .556 can. However, your right I do not have a .556 can at this time so I don't have first hand knowledge, but if it makes you feel better I am buying a .556 can from Thompson Machine (sixteen) and will have it in a few months. 4. As for "a 556 weapon kicking my ass and needing weights", I think this judgment is a bit abusive and irrelevant. I never stated that I could not shot the rifle before the block. I am simply trying to make my carbine build the best that it can be and am doing so by trying out new products? If sharing my experiences offends your sensibilities then sorry you feel that way. |

How do you know it ran cooler, and how much cooler? Temps please. albatrossarmament - Temp specs: I do not have an infrared thermometer but plan to buy one next week Harbor Frieght is selling one for 19.99 in their black Friday sale (yeah I'm a cheapskate). Once I have it I will get some temps for you. Thanks for asking BTW I get a new tool out of this and a trip to the range, win win. For now all I can tell you are that it was cool enough for me to hold the bolt and touch the bolt face w/o gloves (see the pic).

Per the website, the coated gas port pieces are too difficult to drill to make the ports larger. How difficult was it to make the ports larger? Not very hard at all, for the suppressed hole all I had in 1/16 (.0625) was a high speed drill bit so I sued plenty of WD 40 to lubricate and keep the bit cool and let the bit do the work. It took about 8 – 10 minutes. The bit was really dull afterwards so I tossed it. As for the Unsuppressed hole I used a titanium nitride tipped No 50 drill bit (.071) again with WD 40 but this bit worked much faster I was through it in less than 2 minutes. It could have been the bit or the bigger starting hole not sure. Also, when I was done the edges of the holes were sharp and protruding so I had to smoothen it with a screw driver. I did not use a file for this because I did not want to damage the protective coating over the rest of the plate. My parting advice use plenty of WD 40 and let the bit do the work don’t press down hard or you’ll break the bit. I've been in contact with the company, saying that I would love to try it in my 300 BLK and even hinting I would send him the bullets he needs and is out of, but no luck.

I use adjustable gas blocks on 2 of my 300 BLKs, using differing settings for subsonic and supersonic and want something that doesn't clog up and is easier to adjust. Yeah I read that to and I also read the bit about needing to have a competent gunsmith install this thing. I installed it in 15 to 20 minutes and most people I know question my competence all the time. My only concern with drilling it myself was the fact that the holes are no longer coated and are bare exposed metal so I’m sure they are going to wear out faster. Good luck on your build, hope it works out for you. |
| Thank you for the detail reply on drilling the gas ports larger. I am visiting their website every week looking for updates. I really want the 3 position adjusting port block to become available: Off, suppressed subsonic, and supersonic not suppressed for use in 300 BLK. I even got a LAR side charger upper for easier bolt manipulation when the gas system is turned Off. |
