The DT Carbine Stock is a drop-in replacement buttstock for AR15/M16/M4 carbines (or comparable platforms) equipped with Mil-Spec profile receiver extensions. It merges the best features of the SLA(R) and CTRA(R) product lines with its new dual tensioning technology, which provides greater strength and security for a more rugged and stable platform that's easy to adjust. The DT Stock is an A-frame style carbine stock that features an auto-engaging friction lock that's reflexive and inert during adjustment. This produces additional tension on the buffer tube, providing extra tight lockup that minimizes movement between the stock's lock pin and receiver ex Mfg: Magpul
