Magpul STR Carbine Stock- Mil-Spec
The Magpul STR (Storage/Type Restricted) is a drop-in replacement
buttstock for AR15/M4 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? thick rubber butt-pad which provides positive shoulder
purchase to prevent slippage even with body armor or modular gear.
Made in U.S.A.
