The Magpul DT carbine stock (brand part no. MAG1377-ODG) is a drop-in replacement buttstock for AR-15, M16, and M4-pattern rifles running a Mil-Spec receiver extension (tube not included), finished in OD Green. It merges features from Magpul’s SL and CTR stock lines with new dual tensioning technology, which applies additional tension against the buffer tube for a noticeably tighter, more rattle-free lockup than a standard stock. The A-frame body uses an auto-engaging friction lock that stays reflexive and inert during adjustment, giving quick, smooth, frictionless length-of-pull changes and added durability against severe impacts.
