Magpul's DT-S Stock Adds Waterproof Battery Storage, More Bulk

November 6, 2026

Magpul has widened its DT Carbine Stock into a new variant called the DT-S, keeping the same Dual Tension locking mechanism but adding a pair of sealed, waterproof storage tubes built into the body.

Key points

  • Dual Tension carries over: the DT-S uses the same friction-based locking system as the original DT stock, holding position on the buffer tube without a second lever while still adjusting through an ambidextrous latch.
  • Sealed storage added: two parallel tubes, each sealed with dual O-rings and rated waterproof to 10 meters, hold up to two CR123 or AA batteries apiece for optics and accessories.
  • Size and weight trade-off: the DT-S weighs 15.0 ounces versus 9.8 for the standard DT, and its width grows from 1.6 to 2.5 inches, though length of pull stays at 3.3 inches on both.
  • Mounting hardware: it includes a no-slip rubber butt-pad with an angled toe, plus an ambidextrous anti-rotation QD socket and footman's loop.
  • Pricing and colors: Magpul lists it starting at $94.95, $25 more than the base DT, with Black, FDE, and OD Green shipping now and Coyote Brown coming later.

Quick take

This is a straightforward upgrade for anyone who already likes the DT stock's locking feel but wants onboard storage for spare batteries instead of taping them to a rail. The added bulk and weight are the obvious trade-offs, and The Firearm Blog says hands-on impressions are still coming once rounds go downrange.
