Manufactured by Magpul Industries
The Magpul STR (Storage/Type Restricted) Stock is a drop-in replacement buttstock for AR-15/M4 carbines using Mil-Spec receiver extensions. The STR features an improved cheek weld and a compact, reinforced polymer A-frame design. Two water resistant battery tubes each store (2) CR123A lithium or (2) AA batteries. A shielded operation lever and friction locking system prevent accidental operation and minimize excessive stock movement for enhanced weapon stability and accuracy. The STR incorporates two sling loops, a reversible push-button QD sling mount, and a replaceable 0.30" thick rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.
NOTE: Friction lock performance may vary depending on the host receiver extension dimensional tolerances.
