I've seen Bear Creek Arsenal barrels maligned here on the hide so I thought I would share this video of mine. I get no compensation from BCA, I'm just impressed with their accuracy. Here is a 16" run of the mill M4 barrel with A frame sight that I used to build a SOCOM SOPMOD M4A1 Block II copy. I easily get 1/2" moa and not just at 100yds. Here is a video of a test fire (gun is for sale on GB as SOCOM SOPMOD) at 350 meters...LESS than 1/2 moa.
