DT Carbine Stock: Rugged Precision for AR-Style Platforms

Revolutionize your AR15/M16/M4 carbine setup with the DT Carbine Stock, an advanced replacement buttstock designed for Mil-Spec profile receiver extensions. Combining the best attributes from the SL and CTR product lines, this stock introduces groundbreaking dual tensioning technology for unparalleled strength and stability, ensuring a robust and secure platform that remains easily adjustable.

Crafted as an A-frame style carbine stock, the DT Stock integrates an auto-engaging friction lock, reflexively engaging during adjustment. This feature heightens tension on the buffer tube, establishing an incredibly tight lockup, and significantly reducing movement between the stock’s lock pin and receiver extension. Not only does this bolster durability against severe impacts, but it also facilitates swift, seamless, and friction-free length-of-pull adjustments on the move.

Experience enhanced ergonomics with a specially designed non-slip butt-pad that inherits the footprint of the SL line and incorporates the optimized curvature from the CTR. Its ambidextrous adjustment lever, rotation-limiting QD sling mount, and a 1.25” footman’s loop add to its versatile functionality.

Key Features:

  • Mounts on Mil-Spec-sized carbine receiver extension tubes
  • LOP-Adjustment Dual Tension Locking System for secure LOP placement
  • Anti-snag ambidextrous control lever for easy handling
  • Enhanced ergonomics with a non-slip butt-pad and sloping cheek weld
  • Side mounting slots compatible with Magpul CTR Cheek Risers for non-AR15/M4 applications
  • Versatile sling mounting options with rear 1.25″ sling loop and integral push-button QD swivel sling mount

Awesome Stock

Great stock, would take this over CTRs now I think.

Nice and Clean

Got this to replace the stock that came with my Del-Ton AR15. I simply did not like how it looked, so I got this. Feels like quality, looks much better. Was a bit of a pain to install (have to pull down on a pin hard with a tool) compared to the one I replaced, but worth the effort.
