Overview

Built for shooters who want a compact, low-profile carbine stock, this drop-in replacement is suited to AR-15/M4 setups using mil-spec receiver extensions. Its short profile, sloping cheek weld, and compact rubber buttpad are intended to keep the rifle easy to shoulder while maintaining a secure feel in the pocket. The ambidextrous release latch and anti-snag design make it practical for both right- and left-handed use, while the 1.25" footman's loop and compatibility with Magpul sling attachments add straightforward carry options. It is a focused choice for users prioritizing a smaller stock shape without adding unnecessary bulk.

Pros

  • Slim short profile helps keep the rifle compact without adding bulk.
  • Rubber butt-pad with rolled toe improves shoulder placement and transitions.

Considerations & Trade-offs

  • Compact profile may feel less substantial than a full-size stock for shooters who prefer more length and surface area at the shoulder.
  • Designed for mil-spec carbine receiver extensions, so compatibility depends on the buffer tube already on the rifle.
  • The receiver extension tube is not included, so this is a drop-in stock only and not a complete setup.
  • Sling attachment options are supported, but the M-LOK QD sling mount is sold separately.
