The Magpul DT Carbine Stock in Flat Dark Earth (brand part number MAG1377-FDE) is a drop-in replacement buttstock built for Mil-Spec profile receiver extensions, with the tube sold separately. It merges the best features of Magpul’s SL and CTR lines with new dual tensioning technology, delivering a tighter, more secure lockup on the buffer tube while keeping adjustments smooth and frictionless. The A-frame design uses an auto-engaging friction lock that stays reflexive and inert while you adjust length of pull, minimizing play between the lock pin and receiver extension even under hard impacts. A non-slip butt-pad, ambidextrous adjustment lever, rotation-limiting QD sling mount, and 1.25-inch footman’s loop round out a stock built for serious duty and range use.
