    My favorite adjustable gas block

    I've used a handful of different adjustable gas blocks, and over the last year or so switched them all out for SLR Sentry units (Sentry 7's until this purchase). Building a new SBR upper based on Faxon's new 10.5" Pencil barrel and wanted to use an adjustable block as this build is going very light weight, including a skelontized low mass BCG. Wanted to make sure I could tune it properly for the lowest gas that would reliably lock back the bolt. Had the new build out this weekend and, as expected, the Sentry 6 performed excellently. 5 clicks open for regular brass .223, 4 clicks for XM193/855, and 6 clicks for Wolf steel (usually on the lower gas pressure side). Works great, super-easy adjustments with no need for set screws, etc. and they just work. Now I need to pick up a few more of these Sentry6's on a few other builds. If you have a need/use for an adjustable unit (low-mass BCGs, overgassed, suppressor host, etc.) you'll be happy you tried the SLR's Sentry units.

    SLR adj Gas Block

    Started buying these about 5 years ago when they were the only one with a detent adjustment. I have 6 of these, decided to stay with them. There quality is excellent. When I find something that works, I tend to stay with it/them.

    What Recoil??

    These gas blocks are great. Combined with other recoil reducing parts, staying on target is only messed up by the shooter. Right To Bear Arms is a great company!

    Makes my ar15 shoot like a 22 mag

    It works like a charm. Reduces recoil by not allowing over gassing of the system!

    really pretty part

    Some things make you feel good about your choices in life. Black version with black gas tube on bead blasted stainless barrel looks as good as wife, (compliment). Still waiting for clear handguards. This is second one, that should say it. Meticulous construction ànd finish, simple, tough-as-nails. Sets up easily, adjusts quckly if needed for application change, bullet weight... Looks like it would clean easily, I don't know. Lazy I guess.
