SIG's M400 is the company's direct impingement AR-15, and the Forge is the configuration built around solid fundamentals rather than a long features list. The 16-inch barrel in 5.56 NATO is the classic American carbine setup, legal without a tax stamp, ballistically efficient, and handy enough for defensive use, hog hunting, and general range work. A free-floating M-LOK handguard is the current standard, letting you mount lights, lasers, and bipods directly while keeping the barrel unstressed for better accuracy.

This one wears a distinctive green finish and accepts any standard AR-15 magazine and accessory you already own.
