Did some substantial research before deciding on this SLR gas blockIt is considered one of the best if not the best adjustable gas blockI will have to report back after using it more rounds. Others reported using it for thousands of rounds without any seizing

Slr rifleworks makes in my opinion the best gas block around. Fit, finish, and function are flawless. Have two of these and plan to put them on my other two Ar-15s as well. Highly recommend these for any build that you are trying to fine tune cycling and recoil.

Works as it should. It was very Easy to install. The Instructions are easy to understand. I really like that you have audible clicks when backing adjustment screw in or out.I believe this is one of the best gas blocks money can buy!

The Sentry.750 adjustable gas block works as it should, very happy with it. The only complaint I have is ordering through Optics Planet. Had ordered a few parts from this company and it took up to 13 days to receive them.

For my ultimate AR15 build I chose the SLR GB7 to go on a Core 18” barrel in 6.5 Grendel. Makes sense to put the best on the best. Love the SLR gas blocks. Solid. Great price and super shipping from OP. The best of the best too.

I have several of these gas blocks on various builds and they’re great for tuning your suppressed builds and AR10 builds. Very well machined…has a very positive click when adjusting your gas setting. These are the best on the market in my opinion.
