The SIG516 G2 is SIG SAUER's short-stroke gas piston rifle, using a captured pushrod system with an adjustable four-position gas valve rather than routing hot gas back into the receiver. That keeps the bolt carrier cooler and cleaner, which matters most when running a suppressor or a high round count.

This Pro configuration is chambered for 5.56 NATO with a 16-inch barrel, a free-floating M-LOK handguard, and a black finish. It is a rugged, well-proven duty carbine from a company with deep military and law enforcement roots.
