Excellent choice for a lightweight build (18/12/2015)

I bought this barrel for a lightweight AR project and assembled it with a BCM KMR Alpha tube. The completed upper assembly is just incredibly light weight. It moves around so much faster from target to target. The accuracy is very, very good. Iâve only run a few loads through this particular gun, so I canât say itâs close to match grade or not, but I have no complaints. Zeroing sights and red dot was easy and trouble free. Assembly, also without a hitch.

Awesome (21/03/2016)

Awesome lightweight barrel, after break-in was shooting 5 shot groups at 1/4 MOA @ 100 yards. Very surprised. Was my 1st AR build.

Lightweight (02/07/2016)

This thing is definitely lightweight. If you have a bumpfire stock, it can bump fire 22's with some technique (minus optics w/CMMG 22 conv kit). It is also incredibly thin. I was worried that if I did not have a thin handguard it would look unbalanced.

This barrel is pretty precise at 25 yards with 22's (plenty good for squirrels) and handled .223 ammo without any worry. It will kick a little more than usual, but that is to be expected. For me that was encouraged.

Buy with confidence (17/10/2016)

I bought this for a light weigh build. I put a 15" Midwest Industries rail with Daniel Defense fixed irons. I put a clamp on Daniel Defense low profile gas block as well. All in a shade under 6 pounds. Barrel was broken in with Black Hills 69 grain match BTHP. First 100 rounds after break in (50 round break) it shot 1.5 - 2" groups. Not bad but wanted a little more. After 300 rounds of all 69 match it shoots 3/4 all day long.

I shoot 62 grain Gold Dot bonded now and it shoots flawless 3/4 inch groups. Shoots about everything in the 3/4 to 1.5 range. The barrel seems to do well with 62-77 grain.

Mine was very well made with flawless finish. My only complaint as it has been noted was the 1-8 marking on the barrel was cut leaving bare metal. It does rust if you don't watch it. This is a patrol rifle that spends many days in the trunk of a squad. Hot in summer bitter cold in the winter. Barrel shoots the same at 90 degrees or 0 degrees. After 2 or 3 times of getting rust out with steel wool I covered the markings with fingernail polish. No problems since.

Good barrel for a light weight gun at a good price. I have close to 3000 rounds through mine now and rifling still looks great. Many rounds left to go down the pipe
