Quality

Was looking for a low cost, low pro for a “truck gun” build. Wow! Was surprised at the quality and machining! It’s spec’ed out exactly and surprised by the fit! Well done!!!

I like it and will keep a few on hand

I've used this product converting some SIGs for a customer. Easy to use and worked fine. I'll keep a few in stock in the future.

No problems

I used this low profile gas block to go under a hand guard upgrade on a DPMS 5.56 . Easy to install and great quality .

Good quality and price

I've used half a dozen of these on builds and only had one issue with fitment, which I think was due to tolerance stacking and the coating on barrel and block. On all the rest the block fit well, tight fitting but able to be installed on the barrels by hand. I've used them on Colt, FN and Ballistic Advantage barrels with no issues. Having built a few hundred rifles at this point I've noticed no difference in performance between Brownells, Geisselie and Badger gasblock when it comes to performance. I don't see any advantage in a gas block of the same design that costs two or three times as much.

Worked great

Installed this on my 16" Brownell's Nato Barrel. No issues at all.

5 star gas block

Used this gas block to help trim some fat off my rock river operator 2 at 8.1 lbs without accessories it was a bit heavy for me this gas block was one of the parts I used to bring the weight down the hole for the roll pin was straight no problems with the set screws the block went on easy and still a nice fit planning some builds soon and will use this block again no need to spend fifty bucks or more for a gas block when for less than twenty this one works just great good job Brownells.

Easy install

Slick coating made installation easy. Dtente holes and gas hole lined up perfectly with my Wilson lightweight barrel. Very quick and easy installation. Also installed one on a LaRue Stealth barrel. Same result.

perfect value

Very well done for the price. The batch of 10 I ordered exceeded my expectations.

Great value and nicely made.

For the price this gas block is hard to beat. I installed two on two different BA barrels and they fit perfectly. I dimpled the barrels for the set screws and used permanent thread locker to secure them. Very similar in design to the MK 12 gas block so this is perfect for near-clone projects. No markings or logos which I prefer.

AR-15 Gas Block Nitride .750 by BROWNELL

Doesn't include a roll pin. I do carry an assortment of roll pins in my shop so not such a big deal for me but the hobbiest may have a problem.
