SABERTUBE-QD-M-KIT-BLK) combines a lightweight Sabertube receiver extension, a QD end plate and the BAD-LBS lightweight butt stock for AR-15, M16 and M4 lowers. The tube carries a dimpled pattern, and the lightweight design eliminates the need for a castle nut. The butt stock has a built-in non-rotating QD and a Grade 5 titanium stock screw. It is built for shooters chasing a lighter carbine setup, and it is made in the USA.
