Heavier buffer and spring helps slow down the action but does not solve the issue of being over gassed. That's why suppressor optimized barrels are getting more popular. For people who don't want an adjustable gas block. However, you can set and forget an adjustable to run how you want it. You don't have to constantly adjust for suppressed or unsuppressed shooting. The other option is a BRT EZTUNE gas tube. They are supposed to last 4-5,000 rounds before the hole starts opening up.

Quoted: Any downside to tuning with heavier buffers and stronger buffer springs instead of adjustable gas blocks? (Besides the obvious of more gas to the face.) Really don’t want to go that route if I don’t have to. depending on your level of "tuning" you may be reducing your reliability zone when you have a dirty gun, cold temps, weak ammo, etc. |

Have you considered an adjustable bolt carrier group? No gas block installation required. Also like the poster before mentioned, barrels gas ported for suppressor use. Also there are smaller diameter gas tubes out there. I chose a Bootleg BCG for some of my suppressed SBRs and it works for the cans I use (SiCo Saker & Omega).

Quote HistoryQuoted: I guess my question is: Is it hurting anything to be over gassed if you’re compensating for it with heavier burger and spring? More pressure and wear on the inside of the gun is what I have read. All the gas will still be either coming out of the charging handle or ejection port and it won't be pleasant. |

Quote HistoryQuoted: I guess my question is: Is it hurting anything to be over gassed if you’re compensating for it with heavier burger and spring? Yes, you're increasing the wear on your receiver and bolt and getting more toxic gas in the your eyes and lungs plus a sharper recoil impulse. I don't know why the industry hasn't caught on to the fact that suppressors are everywhere now and consumers are looking for solutions that get it right the first time with an appropriately sized gas port for the application and not a solution to the problem caused by their gaping .082 Noveske or LMT gas port requiring an AGB that fossilizes in carbon if you don't clean it every 500 rounds. Flow through suppressors kinda solve some of the problem but they don't reduce sound and flash signature as well as baffled designs. Just give us appropriately sized gas ports! Fuck. |

For every one dude suppressing their AR, there’s a hundred other guys who’ve never heard of Arfcom and still think you need a “Class III License” to own a suppressor who’ve bought the same rifle/barrel and intend to feed it a steady diet of the cheapest crappiest weakest combloc steel case crap they can find. What’s better? Dealing with that one dude who probably knows what’s he's doing and understands how to mitigate an “overgassed” situation or dealing with the hundred other guys clogging up your CS phone lines and email org box because their gun can’t make it through a 30 round mag without shitting the bed? From a business stand point, it’s a numbers game, and businesses are in it for the numbers. That’s not even factoring environmentals and half a dozen other variables manufacturers have to account for if they don’t want to spend their days replacing products that won’t perform in every situation imaginable. Some of the higher end manufacturers can do it because their products are either too expensive or too hard to find (or both) that there’s relatively little chance a “newbie” will ever buy one. Even in that case, some have gone down the “hog out the gas port to appease every swinging dick” road. To be fair, I’ve never had a 5.56 AR that was so overgassed I felt the need to install an AGB. It’s possible, but things have to be pretty extreme before you start seeing actual malfunctions induced by too much gas in a 5.56 AR. Sure, you’ll deal with increased blowback and a sharper recoil impulse, but it’s generally not horrible and can be mitigated to some extent with other parts. Keep in mind, the military does not use AGBs on basically any of their suppressed AR pattern DI rifles and that’s with gas ports spec’d to a good middle ground that’ll support function in almost all environments, suppressed or unsuppressed. That is going to mean you’ll likely see a bit more gas and a bit sharper recoil over a fully tuned adjustable operating system (especially with shorties like the CQBR). |

A heavier buffer can reduce bolt velocity through increasing inertia but it won’t delay bolt unlocking and extraction as much as throttling the gas impulse will. Spring tension is probably even less impactful. The spring is mainly to store energy to strip the next round. But it does add a little resistance throughout the stroke once inertia is overcome. Once extraction breaks the seal of the case, gas is flowing out of the chamber until the suppressor blows down. Bolt weight and spring add most of their impact after that. For a given suppressor, barrel port & length, cartridge load, and person’s gas sensitivity it could be enough. But gas throttling at the port is usually more impactful.

Sounds like the choice is the buy an expensive barrel with a smaller gas port or deal with all the headaches of an adjustable block.
Whole thing is kind of making me not even want to fuck with a suppressor at all lmao. I just want a KISS setup and it sounds like that just doesn’t work or happen when you add a suppressor. |

How do you define expensive? What length barrel are you looking at? Expo Arms barrels at Primary Arms have decent gas port sizes (especially the 10.3 and 11.5), and they are chrome lined and awesome quality for the price. Black River has Nitride barrels for $200 with decent gas port sizes. |

Bought one of these, change hand guard to Magpul SL. You can change gas with your fingers, 3 settings. No gas, 1/2 gas, normal gas. It's actually amazing how quiet an AR is with no gas so it's a bolt action. https://adamsarms.net/product/upper-p1-5-56-11-5/ |

Suppressors add complexity. Everybody wants a magic solution. You can spend $$$ on a flow-through can. Or get a YHM Turbo K and with the $ you save buy a spare BCG and put a $40 Rubber City Armory adjustable gas key on it. It’s a (mostly) one time PITA to adjust. But you can swap tuned BCG in with can, and go back to factory without can. For more $ you can buy a Bootleg adjustable BCG. They vent instead of throttle gas. You can wait until your can gets in to see if you feel you need gas tuning. |

2 of my ARs are run supressed 99% of the time. 1 is a 14.5" triarc track (mid) with a BRT gas tube, sprinco blue, H1 and a gas buster charging handle. On that one I have to swap to a std buffer to reliably cycle brass cased ammo without the can. The 2nd is an 11.5" faxon gunner (carbine), adjustable gas block, std spring, H1 and a vltor charging handle. I adjusted it to just lock back on brass with no can and then opened it one more click for a reliability margin. With a recce 5 I notice more gas with the 14.5". It doesn't blast me in the face or anything, but it's certainly more noticeable. YMMV
Correction- the 14.5" has a H2 suppressed and a std unsuppressed. |

I've got an older 11.5" BCM upper that I shot suppressed for awhile with an older gemtech trek (no idea if its ultra high pressure or not). I found it to be extremely overgassed. I cut down the the FSB for a low pro rail, so an AGB wasn't really an option, and at the time, BRT was doing gas port inserts, not the gas tubes they do now. I ended up with the Gemtech suppressed carrier. Works great. 2 settings, regular and suppressed. Another option is the bootleg with 4 settings. I don't shoot this upper much anymore because I built a 13.9 I shoot the most. But realistically, I would do nothing until its finally approved. Or get some range time on it as is and see how it is if your range does conjugals. What is your current spring/buffer setup? I think you'd be good to upgrade to at least an H, maybe an H2 depending what ammo you shoot most (regardless of the silencer situation). Cold weather/weak steel case being your limiting factors. Also add something better than milspec CH with the little shelf that seals up a bit better. Anything will work. Geissele, radian, etc. I would be prepared for the following options: 1. Do nothing. But I think you'll get sick of gas in the face pretty quick. 2. Upgrade buffer/springs (especially if you are using carbine buffer). Sprinco Green/A5H2 is on my full auto lower and most uppers cycle great on it. Unsuppressed and steel case won't fully cycle depending on the upper. Everything cycles with a silencer, even steel case. 3. Adjustable carrier. (gemtech/bootleg) or 3. BRT gas tube (once you settle on spring/buffer) I prefer mine to run steel case suppressed (maybe not unsuppressed) and full power brass unsuppressed. I shoot suppressed all the time and this is a good spot for me. |

Rifle Speed gas block.
I have used every solution out there and choking the gas off at the port is the best option. I take it a step further and use low mass carriers in conjunction with adj blocks - the low mass carrier further reduces the amount of gas needed to cycle. |

The likely answer to that is no, but in the event you do, that’s when you should start looking for fixes. I personally wouldn’t own a 5.56 AR that had a gas port so large it induced malfunctions when suppressed. In that scenario, I’d be buying a new barrel/upper, although an AGB would also be an option. |

Temps drop too low or the gun gets too dirty, and you’ll start experiencing malfunctions. Not a huge deal for target/range only guns (I have a target/bench oriented 6mm ARC build with a LW carrier and AGB), but probably not the best for serious use. ETA: Just to clarify, I’m talking about the LW carrier and gas tuned to the ragged edge of function. While I’ve never used one of the RifleSpeed AGBs, I'm sure they’re perfectly suitable for duty use. |

I've got a 10.3 crane spec with a JP SCS H2 and an LMT enhanced BCG and the gas from shooting suppressed is not nearly as obnoxious as the noise from shooting unsuppressed. It could probably run a little smoother suppressed with a reduced gas port but an AGB is a non-starter for me and I haven't found any barrels that meet all my criteria without getting into custom so for now it's good enough for me. Just steer clear of notorious gassers like LMT and Noveske and you should be fine.

Quote HistoryQuoted: AGB is the cheapest, most effective, most versatile, and easiest solution, in my humble opinion. |

I threw a slash xtra heavy buffer and matched spring in my LMT MRP and it ejects at 3:00 while suppressed. No suppression it still runs fine with this setup. Without it, it was extremely overgassed when suppressed. No more gassy than other guns I have with AGB.

From what I gather, BCM's 11.5" gas ports are bigger than you'd want for a suppressed upper, but not as big as many others. Hoping YHM did a good enough job with the Turbo T3 at mitigating blow back to at least some extent. I already have an S2 buffer and Sprinco blue spring ready to go in. AGB is the last thing on my list I want to do. The idea of replacing an essentially fool/bomb proof non adjustable gas block off and putting an AGB on makes me cringe. |

I’ve had a lot of adjustable gas blocks. The current champion is Riflespeed. 12 settings if you need/want them. Simple, effective, and durable.

I wouldnt be as concerned as you are about an AGB, but there are other options that have been mentioned. Throw an H2 in it and see how it goes. If it's not enough for you then grab a BRT tube. You can configure them to suite your needs/platform. They aren't going to magically fail at 5k rounds. If/when it starts to get worn and you notice that there's increased gas, replace it. Start with a std spring and H2. See if it cycles unsuppressed (it should). Once you get your can throw it on and see where you're at. IF there are issues we can look into it further.

I wonder why more people don't run these? https://yhm.net/new-products/suppressor-gas-block/ Seems like you could just drill it to around .06" or so and have a generally well tuned upper with the peace of mind of not having to run an AGB. What am I missing aside from obviously not having the ability to fine tune the gas? (Seems like .062 or so would still be a hell of a lot better than .07"+) |

Quote HistoryQuoted: Sounds like the choice is the buy an expensive barrel with a smaller gas port or deal with all the headaches of an adjustable block. Whole thing is kind of making me not even want to fuck with a suppressor at all lmao. I just want a KISS setup and it sounds like that just doesn’t work or happen when you add a suppressor. The KISS solution has already been mentioned. It is the BRT gas tube. You can have any sized gas port you want with no moving parts. They work great. A bit expensive for a gas tube but absolutely worth it for a well tuned gun. As other mentioned you can just run it stock fine most likely. All that said I prefer a high quality AGB that I can set and forget though I might splurge on a riflespeed one day… then again I might not as I amost never shoot without my can. That yhm gas block would prob work great on a always suppressed gun. |

Adjustable gas block ftw.
I'm so glad I bought up those Joe Bob outfitter adj gas blocks when they made them. $25 got you a regular gas block that they literally just drilled/tapped a set screw into. So far the few I have used have turned out perfect. Abmnd here I spend $100+ on JP ones originally

(Seems like .062 or so would still be a hell of a lot better than .07"+) Mainly the vagueness of the "55% smaller" gas port hole. The gas blocks are designed to be larger than the gas port on the barrel, so who knows what the equivalent gas port size is and it sounds like it requires some trial and error drilling the gas port hole to the desired size. |

Found someone on Reddit say they bought one and it was .055”. Thinking of buying one and drilling to .06” or so and rolling with it. Still more gas than necessary but way better than .070”+. |
