Great barrelReview by
Great barrel shoots wonderful very accurate shots flat perfect. (Posted on 12/21/2016)
Very accurate barrelReview by
My AR build is comprised of an M16 bolt carrier, A5 buffer system w/A5H2 buffer weight, and this barrel. Very soft shooting as it utilizes rifle length gas system like an M16 while the HBAR profile, coupled with a nice brake, help keeps the muzzle flat during rapid firing. Out to distance, nothing but less an 1 MOA, even with my Geissele SD3G trigger. Looking to build another rifle with this or an intermediate barrel as it's much more easier on the BCG vs carbine or mid length gas barrels. I'm sold. (Posted on 8/22/2016)
Just buy itReview by
I first became aware of this barrel via a review on a popular AR15 site and was very intrigued. It's pretty gutsy to offer an MOA guarantee on a barrel, but that's what I was looking for in my 16" "recce" rifle so I bought it.

I'm a pretty new shooter and brand new to precision shooting, so I expected to be just shooting barely under 1MOA because of my lack of skill. Nope. Shot three different 5-shot groups ranging from 0.4-0.7MOA off a bench and bipod with no rear bag and shooting Black Hills 77gr OTM.

This barrel SHOOTS! Really looking forward to growing into the world of semi-auto precision shooting with this barrel. They guarantee 1MOA with match ammo; as far as I'm concerned they should have guaranteed half-MOA. Quality product.

ExcellentReview by
Got this barrel mounted and after a 10 shot break in and zero I shot 2 3 shot groups under .5". Needless to say I am very pleased with this barrel. (Posted on 4/12/2015)
