    Complete Upper

    I stopped by this booth at the NRA show and got the run down of their product line. I figured I'd give them a shot. It was well worth it. I havent put any rounds through yet, but the quality looks and feels better than I expected given the cost. Looks great and is super light! Nice upper, definitely recommend.
