Magpul STR (Storage/Type Restricted) Collapsible Stock (Black)
The Magpul STR is a drop-in replacement collapsible buttstock for AR15/M16 carbines using mil-spec sized receiver extension tubes. A storage-capable version of the CTRŽ, the STR has improved, wider cheek weld and two water resistant battery tubes on a compact, reinforced polymer A-frame design. A shielded operation lever to prevent accidental operation and a supplemental friction locking system to minimize 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 other field gear.
