An adjustable gas valve allows operators to increase the flow of gas when using lower pressure ammunition or when adverse conditions require additional energy. Reduced flow and the off-position enhance the use of suppressors. Barrels feature an A2 flash suppressor and are threaded 1/2×28 TPI, allowing the SIG516 to adapt to a number of aftermarket accessories and suppressor mounts.
Whether you’re left- or right-handed, there should be no compromise in shooting performance. The SIG516 features an ambidextrous selector, magazine release and charging handle.
