Product Description

The SIGM400 rifle builds upon one of the longest serving military and police rifles in history by combining a direct gas impingement system with well-designed improvements and features. The SIGM400 is safer, more reliable, and one of the few rifles that can pass the Military’s “Stuck Bullet Test”.
