I have an upper receiver that has around 100 rounds on it. It is a very accurate upper and shoots sub moa with several rounds. It likes the PMC XTac 55, IMI 77Gr Razor Core, and it loves the Federal GMM 69gr and it shoots closer to 1/2 moa with those. Build parts are listed below. Everything is in like new condition.
