The SIG522 provides the avid sport shooter plenty of action on a classic military style platform that give the look, feel, and dependability of our full size SIG556. The Commando offers the same features as the original SIG522, with an anodized, alloy upper receiver and an M1913 rail mounted for the easy addition of optics, sights, lights, and lasers. A folding, telescopic stock provides a strong, stable platform for shooters. The Commando features an inert training suppressor mounted by standard 1/2 x 28 TPI threads. The inert tactical trainer can be removed and the threaded barrel also accepts many of the most popular flash suppressors and sound suppressor mounts on the market. The Commando accepts 10- and 25-round polymer SIG522 magazines. Weighing in at just over six pounds, the Commando is lighter than a standard SIG556 and enables longer training time with less fatigue, but still retains enough weight for realistic training purposes.
