Good barrel, Great price

by -

Bought this barrel on sale. Fired 145 round through it on my first range trip. 0 malfunctions of any kind. Seemed to hit constantly out to 100 yards, did not bring a target to zero my rifle with as I was just function testing, so I was using the zero on my red dot for a 300BLK build but it hit in the same place everytime, though not on the dot obviously. Will zero it next range trip.
