    Excellent shipping

    I received my upper extremely quick, which is fantastic. The piece looks great. I'll make a follow-up post once I get my platform assembled and tested. But as far as the order process goes, Bravo is great.

    Impressed

    The upper was very clean,well machined, very tight tolerances. I had to heat it slightly with a hair dryer and tap the barrel in slightly with a mallet. It fit my spikes, stag arms, and dpms lowers with minimal wiggle. Even less then the bushmaster and aero precision upper i already had. Over all im very happy and will buy this upper again.

    Clean

    Upper arrived in perfect condition. The tolerances are very tight which is nice; even with Aeroshell grease I had to lightly tap my 300BLK barrel into place. The tight tolerance will make it very accurate.
