The DT Carbine stock is a drop-in replacement for firearms equipped with a Mil-Spec receiver extension tube. Featuring dual tensioning technology, combining the best features of the SL and CTR stocks, the DT Carbine stock provides greater strength and stability that's super easy to adjust. The A-frame style carbine stock features an auto engaging friction lock providing extra tight lockup on the buffer tube without the need for a manual secondary friction lock. The result is increased durability in case of severe impacts and quick, smooth, and frictionless length-of-pull adjustments on the fly
