Adams arms guys will be visiting this sat
Posted: Tue Mar 04, 2014 8:50 pmYup, the makers of "piston uppers" systems for about 8 various AR15 manufacturers will be showing their stuff at Everything Weapons in Cool Springs, beginning(I think) at 1000 am Sat. I do not know if they will be selling, but maybe they will take orders. If you ever wanted a cool, clean "piston" upper for yer AR lower, this might be the time. G'luck. Remember the upper w a 16" bbl is easily, and legally interchangeable w a registered lower.....
