I put this on a DPMS barrel with a much larger block because I was installing a Spear Free Float Hand Guard and it was super easy and fit perfectly!!!! 3 magazines through it so far and it worked flawlessly!!!! Highly recommend the gas block hand guard and AT3 Tactical!!!!!
Not much to say here except this is a simple, rugged product. Good finish, minimal took marks, great fit and a decent price... A1 in my book.
Installed in no time. Fits perfectly under my new handguard. The product i received did not have the milled flutes on the side as shown in the picture though. No biggie.
Works great at a budget price point. Excellent value, thanks so much AT3!
This fit under my Colt free float handguard.
This gas block was the only gas block that would fit under my hand guard. Works perfectly. Would recommend.
