Awesome product and good delivery service. This Sentry 7 Is the second one that I have purchased. It functions flawlessly and once it has been tuned to your rifles gas pressure. It is very reliable and consistent.

I’ve ordered and installed 2 of these blocks now, and I love them. The first one went on a DPMS LR-308T (16” carbine gas), which is extremely over-gassed.The fact that they can be easily disassembled for cleaning and/or maintenance (if it’s ever necessary…) is a big plus for me.Detents are positive and audible, also a plus in my book. No set screws to loosen and leave you stuck.

I use SLR's Sentry adjustable blocks (almost) exclusively for my project builds for the last several years. Unlike some other adjustable blocks, no messing about with double set screws, single set screws, impossible or difficult to access adjustments. The SLR Sentry adjustable blocks are simple to use, simple to access for adjustments, and very rugged in use.

SLR adjustable 15 settings gas block are fantastic gas block with the titanium are the best gas block i have used. Each setting on the gas block clicks into place and stay in place witch not all do. The titanium is lite weight and very strong too with a good look too

Installed this gas block on my 16" PSA barrel that was over gassed. The SLR Agj gas block really calmed my AR down. The clicks are positive and felt. Side note, if you buy a T-handle for adjustment under hand guard, it is a 2mm.

Buy once, cry once, spend the money and get the SLR! I’ve used these set screw and clamp on models for multiple suppressed builds. SLR makes quality stuff and their customer service is top notch too. The fine tuning of these gas blocks with the great feeling ‘audible clicks’ is my favorite part about them. Dial it in and forget it. Good to go!
