I use this barrel for my 300 blk AR pistol set up and I zeroed it to 50 yards with a vortex red dot and vortex magnifier. I was able to hit bullseye multiple times. Great barrel with good accuracy and it's built tough. I ran through about 500 rounds through it and so far it's still very accurate. For the price, it's hard to say no. I strongly recommend.

I bought this for my 300 blk build and it shoots great. I'm actually buying another barrel for a 5.56 build.
