How much need is there for an adjustable gas block on a 10.5" blackout for suppressed shooting? Also, I'm guessing a gas buster or similar charging Handle is worth looking at? Any other mods you folks recommend? Thanks for the help! |

The upper I have currently does not have an adjustable gas block, but nor do I have a suppressor yet. I'm wondering if I can try as is, or change gas block before suppressor gets here.
I'm very open to suggestions of which gas block also! |

I use the bootleg adjustable carrier since I have a regular FSB. A gas-relieving charging handle could be a good idea if you're expecting excessive gas, but people say they're hit and miss. I like my Radian SD though.

I've got an adjustable gas block on my 8" .300 gun and it works great for me. I run the gun 100% suppressed and always subsonic (for now). I dialed in the gas block starting with very low gas and opened it up one click at a time until it would cycle and lock back then went one click further for good measure. It's been perfect since then and is very soft shooting. I don't notice much gas to the face at all and I'm shooting indoors most of the time. For reference I'm running a SLR Rifleworks gas block and GA Recce 7 can. If you're building your upper I would consider the AGB.

I like my Radian SD though. 8.5" PSA: upgraded the buffer spring to get away from cheese grater noise. Runs supers and subs like a champ without any other changes. I wish I could tell you why they do what they do. Run some through it to see if you even need it. |

A properly ported 300BO in that barrel length shouldn't need an adjustable gas block to function in all 4 modes. It is useful if you run mostly supersonic suppressed to tune the lock time and soften extraction.
The Bootleg adjustable bolt carriers work great and are more convenient to use than an adjustable gas block. Plus if need be you can swap them easily to another upper for diagnostics or to try out adjustable gas. Adjustable gas blocks are cheaper. You have to run the adjustment in and out periodically to minimize carbon locking in the adjustment. Most people eventually find a setting and leave it. |

My 9” aac barrel runs ok with the gas block it came with. It runs suppressed and unsuppressed.
It could definitely benefit from an adjustable gas block and I will probably get one eventually. It’s not an urgent upgrade, but it is something I want to do. It’s definitely over gassed. My opinion on adjustable gas blocks is they have many pro’s and only one con, cost. I love my adjustable gas block on my 5.56. The only reason my 300 blackout doesn’t have one is that it came with one. |

Go with an adjustable gas block and don't look back. Once adjusted correctly, there's no need for a gas buster. Quote HistoryQuoted:
