The Magpul DT Carbine Stock is a mil-spec drop-in replacement buttstock engineered for AR15, M16, M4, and similar carbines that run a mil-spec receiver extension. If you're upgrading an AR platform rifle and want tighter lockup, smoother adjustments, and a more stable shooting platform, this is the stock that delivers on all three fronts. Magpul combined the best engineering from their SL and CTR product lines and added their new dual tensioning technology—a system that creates extra tension on the buffer tube to eliminate the play and rattle that can develop during hard use or after impacts.
What sets the DT apart is how it handles the adjustment problem that plagues cheaper stocks: the auto-engaging friction lock keeps your length of pull exactly where you set it, with no secondary creep, while the ambidextrous adjustment lever lets you dial in your preferred LOP quickly and smoothly whether you're geared up or in shirtsleeves. The non-slip butt-pad uses the same footprint as the SL line but borrows the optimized curvature from the CTR, so it shoulders naturally and works better when you're wearing body armor or a plate carrier. Magpul also integrated a rotation-limiting push-button QD sling mount (compatible with standard 1.5" swivels) and a 1.25" sling loop, giving you flexible attachment options without the snag hazards of older designs.
Made in the USA with a rock-solid construction, the DT Carbine Stock fits any mil-spec receiver extension from Colt, LMT, Ruger, S&W, SIG, and other major manufacturers. Note that it will not fit commercial-spec tubes—verify your rifle's tube size before ordering. Compatible with Magpul CTR Cheek Risers if you want to run an optic with an extended stock, and it works seamlessly with Magpul's ASAP and other receiver-mount sling systems.

The DT Carbine Stock is designed for any AR platform (AR15, M4, M16, AR10, M110, SR25) equipped with a mil-spec receiver extension. It is not compatible with commercial-spec buffer tubes. Verify your rifle's tube size before purchasing. It will fit receiver extensions from manufacturers including Colt, LMT, Ruger, S&W, SIG, Armalite, and others, though the receiver extension is not included.
The DT Carbine Stock combines the best features of Magpul's SL and CTR product lines and adds dual tensioning technology, which creates extra tension on the buffer tube to eliminate play and rattle. This means tighter lockup, reduced secondary movement of the stock on the tube, and greater durability during hard use or impact. The auto-engaging friction lock also holds your length of pull setting without creep, and the non-slip butt-pad incorporates the optimized curvature from the CTR for better shoulder fit and body armor compatibility.
Yes. The DT Carbine Stock features an ambidextrous adjustment lever that allows you to change your length of pull quickly and smoothly in the field. The auto-engaging friction lock ensures your chosen setting stays in place without secondary creep, so you don't have to readjust mid-use.
The DT Carbine Stock includes a rotation-limiting push-button QD swivel mount (ambidextrous) that accommodates standard 1.5" swivels, plus a 1.25" sling loop for non-QD attachments. It is also compatible with Magpul ASAP, ASAP QD, and other receiver-mount sling systems.
