Would I be wise to purchase an adjustable gas block? My first can is In jail till this winter but planning on putting it on my ar for fun and coyotes.wondering if I'll need one for reliability
Here's a,little background on the gun Rainier arms .223 wylde16" match barrel (I think it uses intermediate length gas tube) Rainier arms precision match bcg Spikes tactical heavy buffer AAC 762 SD can |
|
I have a 762 SD as well, and I run adj. gas for these reasons...
I can completely close it for max stealth. I can run a super lightweight buffer. I can cut down on gas blowback, as I am a lefty. And the best reason... I run a plastic buffer when I am shooting without the can... and place a H3 when I have the can in place. All with no adjustment, to the gas system.

There are not a lot of cons when you get the set screw at the spot you want it. Problem with adjustable blocks is that there are no companies that make a block that the set screw does not seize. Like I said it is Not really an issue though once it's set.
I will be putting one on every future upper build. They get all over gassed SBRs working and will make any gun shoot softer. |

My first can is In jail till this winter but planning on putting it on my ar for fun and coyotes.wondering if I'll need one for reliability What do you mean by "in jail"? If you're referring to waiting for the stamp and your paperwork is off, you might be surprised. Wait times have come down a lot in the last year, or so. My Form4 submitted at this time last year only took 4 months. Anyhow, "need" is a pretty strong word when it comes to adjustable gas and reliability. - There are a couple of "problems" people encounter with adjustable gas blocks. One is that many plain old adjustment screws will walk out from pressure and vibration. The homegrown solutions to this is to loc-tite the adjustment screw, or to install a set screw to lock it in. If you are exploring adjustable gas block because you want to adjust between suppressed and unsuppressed, then these "solutions" don't work for you. The common industry solution to that is click detents on adjustment screws, but there are also some who include that second set screw as mentioned as a home remedy. As mentioned above, those detents can seize up from carbon fouling. Not a problem if you're looking for a "set it and forget it" scenario. Again, if adjusting between suppressed and unsuppressed is what you want, then you don't want the parts seizing up. Make adjusting the screw on a regular basis part of your routine. One thing a lot of people are doing is to work the screw in and out each time you clean the rifle. If it's time to remove carbon from the bolt/carrier, then make the parts in your adjustable gas block move to maintain their range of motion space, instead of allowing the carbon to build up until it's tool late. Lastly, there are solutions with preset openings for "suppressed" and "non-suppressed". If the presets match your system, great. If they don't, then you have to try to match your gun's system to those presets. This isn't as horrible as it sounds, as it is just like matching the components of a rifle to the gas flow of a non-adjustable block that we were doing not so many years back before adjustable gas became such a popular thing. Here's the last piece of consideration in making your decision: A "battle" rifle typically is, and should be a little over gassed for reliability. If you get a non-adjustable or a cheap adjustable block that you lock down - if you tune that rifle to the minimum for reliable function unsuppressed - then it will still function suppressed, but both you and the rifle will suffer from extra gas and carbon fouling when shooting suppressed. If there was one solution that was clearly better than any other, the others would disappear. We still have non-adjustable gas and various types of adjustable gas blocks because all of them "work". It's just a question of what product most matches your desires, and what balance of work and result you prefer. My personal choice is click detents, specifically Syrac Ordnance Gen2, but you have to decide what works for you and your rifle. |

Ok thanks guys. Anyone have experience with the seekins precision adjustable gas block? I just installed one on a 16" mid length. Fairly easy to dial in, the set screw is reachable from the front of the block. I was able to move the eject pattern rearwards a bit, and, more importantly to me, stop the case denting I was getting with a standard gas block. I've only got about 100 rounds through it and I have not tried to move or change the setting after I dialed it in initially. |

I was leaning towards seekins simply because I like there products as a whole and also the price point is good. I've heard good things about syrac and slr as well. I'll most likely set it and forget it because I don't have a reason to shoot unsurpressed really once I get my can. And yes as mentioned above by saying in jail i mean im waiting on my form 3 right now. I was told by silencer shop my form 4 should be submitted in the next month |

Because the dealer is already vetted and licensed, by the time ATF gets around to your Form 4, the virtual ATF world already has the can recorded as being in the dealer's possession. I agree on Seekins quality. I wouldn't worry about that aspect, as long as their solution provides the features you want. |

Silencer shop emailed and said they had submitted my form 3 and that my form 4 would be submitted within the next month. I already have the serial number of my can silencer shop had it in Stock. My local dealer had received the info last time I talked to them but they did not have my can in there possession yet. I feel like the seekins will meet my needs but I like to get others opinions on something I'm unfamiliar with. I thank you all for your insight. |
