Absolutely excellent - Adams Arms P2 Upper - 16in Mid Length Gas, 556 Barrel

Perfect execution of the piston upper. Weight is spot on, finish is awesome and even. I can't find any imperfections in the upper. I highly recommend this upper and Adams Arms in general. Barrel is awesome- only thing I'd change is a different flash hider on the end. You get the MLOK rail, with the huge benefit of the gas piston system and ease of maintenance. I've had Sig 516s, Superlative Arms, and PWS- and I rate Adams Arms above all of them for their ease of maintenance and simplicity of operation.
