Excellent, as always |

I've used several Sentry 7 set-screw blocks, and a few Sentry 6s, also set-screw. I ordered this Sentry 7 clamp-on, well, by mistake, thinking I was clicking into the set screw model (my fault entirely).
No matter! Installed on new 458 Socom build. Works excellently, just as all of my previous Sentry 7s. No issues with fitment or staying in place.
Running a KAK 16" 458 Socom barrel, with carbine gas, I wanted to ensure I could tune it properly for the lowest gas that would reliably lock back the bolt. Nicely, it cycled and locked the bolt back at only 4 open clicks, non-suppressed (SBR 350gr TMJ for testing). Waiting on Hybrid in suppressor jail to see how low it will go suppressed.
As with my other SLR blocks, it works great, super-easy adjustments with no need for set screws, etc. and they just work.
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.
