The Anderson AM-15 M-LOK features an M-LOK compatible free-float handguard over the standard AM-15 carbine. The 16-inch chrome-moly barrel, carbine-length gas system, and mil-spec lower are retained. The M-LOK handguard allows light, grip, and accessory mounting without added bulk. Anderson's price point makes this one of the most affordable free-float AR-15 configurations available from a factory.
