This upper is a great buy - Radical Firearms 16 in. 5.56 SOCOM Upper Assembly

I purchased this because i wanted a cheap ar upper to practice cerakote on. The finish leaves something to be desired so coating this would really enhance its looks. I dropped in a bootleg inc bcg and slapped it on my aero lower to test fire. Everything seemed to be perfectly in spec. It shoots excellent. One other thing to consider when purchasing is some sort of rubber rail covers because the handguard rings like a bell when you release your bolt.
