If you are looking for a drop-in replacement buttstock for your AR15/M16 carbine, check out the Magpul STR (Storage/Type Restricted) Carbine Stock. This buttstock works with mil-spec sized receiver extension tubes, and is a storage-capable version of the CTR. The STR has an improved cheek weld and two water-resistant battery tubes in a compact A-frame design made of reinforced polymer. The storage tubes are capable of storing up to two (2) CR123A or AA batteries, and are accessible from the rear in any stock position.
The Magpul STR features a shielded operation lever and supplemental friction locking system to prevent accidental operation and reduce excessive stock movement, allowing for better enhanced weapon stability and accuracy. A premium chrome-silicon lock spring provides positive locking and a long service life.
The STR provides two sling loops integrated into the buttstock, including a reversible push-button QD sling mount and rear/bottom 1.25” sling loops. The STR also includes a replaceable 0.30” rubber butt-pad for positive shoulder purchase. This prevents slippage, even when wearing body armor or modular gear.
