Quality made and reasonable price for the option of adjustability. It went on a 300 blackout pistol running mostly supersonic and a few subsonic for home defense. I would definitely recommend using this product

I purchased the titanium gas block for my Larue Stealth barrel, since the set screw spacing is a little wider than most barrels on the market. My Stealth barrel’s gas port measured .83” for a 14.5” barrel, which would make that particular barrel overgassed if I just put a standard non adjustable gas block on it. The SLR Sentry 7 is extremely well made, great finish and extremely lightweight. I have yet to put any rounds through it, but I’m sure it will work great suppressed and I suppressed. I would definitely purchase this gas block again and recommend it to other people who want to control the gas on their rifle. The adjustment screw has a very noticeable feel when you change to different settings. Gas tube roll pin came with packaging as well.

Alright, so the gas block is premium. The fit and finish is second to none. I was unsure what to expect, but it really is a manufacturing work of art. The tolerance was tight, it practically stays on the barrel without set screws. I am really impressed with the product, but SLR is a disappointment. I have been to reaching out to them by phone, email, and even Facebook. Nobody ever responds! In two months I have yet to receive any for of communication from anyone at the company. My only grip would be with the company’s lack of customer service, the product is excellent but if something where to go wrong I would be SOL. I value good customer service and they fail miserably at it.

Very nice adjustable gas block. Good option for AR pistol if you don't want to mess around with different buffer weights to make your pistol cycle properly. Very easy to adjust with an extended driver which is also very cheap to purchase.

This block is a bit pricey but definitely shows the quality in the craftsmanship. Really nice machining and tight tolerances. Using this on a LaRue stealth barrel which are very accurate 1/2 moa barrels but they run notoriously over-gassed so being able to use the slr block to adjust pressure is a blessing. The adjustment clicks are nice. I definitely recommend this block for those who suffer with over gassed barrels.
