Video—I Have This Old Gun: Colt Model 601 Carbine

Selected by the U.S. Army for specific use with the XM157 optic aboard its Next Generation Squad Weapon competition winners (the M7 and M250 rifles), to unobtrusively secure the former’s potentially bothersome cables out of the way.

Despite having been made popular by John Moses Browning over 100 years ago, his sacred M1911 design has soldiered on into the modern era, and companies like OA Defense are taking to the classic military platform in all-new ways, improving functionality by nearly tripling the design's capacity with double-stack mags, adding optic-mounting capabilities and more.

POF-USA's LMR and P15 BASE rifles are designed to get the company's patented rifle technology into the hands of more users than ever before.

The unmagnified Midas TSP1 from Athlon Optics features an etched-glass reticle and a nitrogen-purged, one-piece aluminum chassis.
