Sig Sauer M400 Tread 5.56mm 11.5″

The 11.5″ TREAD is a very feature rich AR pistol. The 11.5″ barrel is cold hammer forged and provides a very compact platform that makes maneuvering much easier than when compared to a full 16″ rifle. The lower receiver is fully ambi and includes integrated QD attachment points. 

While the 5.56mm round isn’t phenomenal ballistically out of shorter barreled firearms, it is still quite effective. We would recommend the 11.5″ TREAD for someone who is looking for a CQB specific AR at a fairly affordable price point.
