Who This Is For
The Magpul STR is ideal for tactical shooters, competitive marksmen, and home-defense AR builders who want a step up from a basic carbine stock.

Frequently Asked Questions
Will the Magpul STR fit my AR-15's buffer tube?
The Magpul STR is designed specifically for mil-spec sized carbine receiver extension (buffer) tubes. It will not fit commercial-spec buffer tubes, which have a slightly larger outer diameter. Before purchasing, confirm your lower receiver or existing stock uses a mil-spec tube — most mil-spec AR-15 and M4-pattern rifles do, but it's worth verifying to ensure a proper fit.
What can I store in the STR's battery tubes?
The two integrated storage tubes on the STR are sized to hold standard AA or CR123A batteries, making them perfect for keeping spare power for optics, weapon lights, or other accessories. The tubes feature water-resistant seals, so the contents stay protected in wet or harsh field conditions.
How does the STR differ from the Magpul CTR stock?
The STR and CTR share the same core anti-wobble friction lock system and shielded QD sling mount, but the STR adds two onboard water-resistant storage tubes and a slightly more robust A-frame cheekpiece for an improved cheek weld. If you need accessible field storage and a more solid cheek-to-stock contact, the STR is the better choice; if you prefer a lighter, more minimal profile, the CTR is a great alternative.
