    Very fine quality, shipping was ridiculously quick, I’m buying another one soon. They were not lying about sub MOA performance. Works so smooth with the A5 buffer system combined with the mid length gas system. Thank you Big Tex for just outdoing yourselves with communication and top tier customer support.

    Well gassed, decently accurate, high qc/qa barrels at a great price.
