OK, like I need another gun as my wife says, I got 2 big safes full. Well I bought a Aero .308 stripped lower and assembled it with all Aero parts. Now I'm looking at uppers. I want something good at about 300 - 400 yards. What is everyone thoughts on Bear Creek? I been looking at assembling a Aero upper but based on the reviews for BCA upper in 20'' at half the cost, I been looking hard at them. Any input is appreciated.
