Magpul STR Carbine Stock, Mil-Spec

The Magpul STR (Storage/Type Restricted) is a drop-in replacement butt stock for AR15/M16 carbines using mil-spec sized receiver extension tubes. A storage-capable version of the CTR®, the STR has improved cheek weld and two water resistant battery tubes on a compact, reinforced polymer A-frame design. A shielded operation lever and supplemental friction locking system prevent accidental operation and minimize excessive stock movement for enhanced weapon stability and accuracy.*

The STR incorporates two integral sling loops, a reversible push-button QD sling mount, and a replaceable 0.30" rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.

NOTE: There are two basic sizes of M4 Carbine receiver extensions (buffer tubes): mil-spec and commercial-spec. If you have a commercial-spec extension on your rifle, make sure to order the Commercial-Spec STR. Please see the "Related Info" section above to determine which tube you have.

Made in the U.S.A.

    STR Carbine Stock-Mil-Spec

    Posted by Thomas Blackmon on 7th Aug 2021

    This stock combines the rock-solid friction lock of the CTR and cheek weld/storage of the SOPMOD, while still being compact. It was ordered Wednesday evening and arrived on Saturday morning. SKD continues to be an outstanding outfit!!!!!!!

    Great stock, especially for an A5 tube

    Posted by Joseph M on 17th Jan 2016

    If you have an A5 length receiver extension, this is the perfect stock for it. Just the right length, storage, and high strength. Highly recommended.

    Love this stock!

    Replaced my Colt Rogers stock with the Magpul. The swivel socket is too low on the Rogers and perfectly placed on the STR. Plus the storage and superior cheek weld on the Magpul make it the best stock out there.

    A CTR but with cheek weld!

    Posted by May-00 on 23rd Dec 2015

    Love it, I've always been a Magpul CTR stock guy but always hated not having a more direct cheek weld. Hence the STR. Best I've ever used.
