Adjustable Gas Valve
All SIG716 G2 rifles have an adjustable gas valve that can be opened to increase gas flow when ammunition or adverse environmental conditions require additional cycling energy. Gas flow can also be reduced or shut-off for use with suppressors. All barrels are threaded 5/8×24 TPI to accept most popular flash suppressor and sound suppressor mounts, and come with an A2-style flash hider installed.
