The Commando features an inert training suppressor mounted by standard .50 x 28 TPI threads. The inert tactical trainer can be removed and the Commando used in the standard rifle configuration. The threaded barrel also accepts many of the most popular flash suppressors and sound suppressor mounts on the market. The SIG522 Commando is a cost-effective training tool for military, law enforcement or anyone who depends on a carbine or rifle for protection. The Commando offers the same features as the original SIG522, with an anodized, alloy upper receiver and M1913 rail mounted for the easy addition of optics, sights, lights and lasers. A folding stock provides a strong, stable platform for shooters. The Commando accepts 10 and 25 round polymer SIG522 magazines, and weighing in at 6 lb 2 oz. 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.
