I'm really impressed

by -

This is my first Bear Creek barrel and I'm really impressed with it. For the price of their products I had some reservations, but after receiving this barrel I will most definitely buy more. I can't see any machining marks, it's smooth, the nitride finish is perfect inside and out. The chamber is smooth, to can't see any machining marks in there either. Headspace is good to go on the one I received. Another thing I really loved is it already had a dimple for the gas block set screw plus gas block went on nice and tight. I could compare this to more expensive barrels I own.
