Magpul STR Stock

Mil-Spec

The Magpul STR (Storage/Type Restricted) is a drop-in replacement buttstock 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.

Features:

• Mounts on mil-spec sized carbine receiver extension tube (not included) from manufacturers such as Colt, Armalite, S&W, LMT, and others (please see the note below)
• Two water-resistant battery storage tubes located on the left and right sides of the stock
• Each tube will store up to two (2) CR123A lithium or AA batteries
• Tubes are accessible from the rear in any stock position via a hand-removable rubber plug
• Supplemental friction lock minimizes accuracy robbing wobble*
• Premium chrome-silicon lock spring provides positive locking and long service life
• Sloping cheek weld provides a wide contact surface for user comfort
• Shielded release latch prevents snagging and accidental operation
