HK416 vs M4

Heckler & Koch 416 Vs. Colt M4 - Over the Beach SOCOM Test. The folks that know me on LL are aware that I’m a big HK fan and especially of this rifle in particular. The frogman’s test was conducted both with stock rifles. Awhile back I put my buddy in touch with an outfit that retrofits your AR-15 upper to a single piston system to avoid this catastrophe. I hear he’s very happy with it and it functions fantastic.
