Spikes tactical 300bo 10in upper - Spikes Tactical 300 Black Out 10in Forged Upper Receiver

Well built upper receiver, but I made the mistake of buying the 10in full picatinny rail and A2 flash hider...loud and throws gas in your face, which I full expected...should have purchased one without a flash hider, barking spider, or a PSA Custom Series .30cal fluted flash can to expel the gasses forward of the shooter and reduce the muzzle blast. Oh well, I learned and ordered the PSA flash can and slimmer M-Lok rail. Nothing against the upper, just my fault with the lack of research.
