Magpul STR Carbine Stock

The Magpul STR (Storage/Type Restricted) Carbine Stock combines the enhanced cheek weld and friction lock system of the CTR with dual water-resistant battery storage compartments. Built on a compact, reinforced polymer A-frame design, the STR provides 12.3 ounces of feature-packed performance for shooters who need onboard battery storage for optics and accessories. Each of the two side-mounted tubes can store up to two CR123A lithium or AA batteries.

The STR features the same supplemental friction lock system that made the CTR legendary, eliminating stock wobble entirely when engaged. The stock incorporates two integral sling loops, a reversible push-button QD sling mount, and a replaceable 0.30 inch thick rubber buttpad for positive shoulder purchase. The 3.3-inch length of pull adjustment range accommodates shooters of different sizes and allows optimization for different gear configurations.

Users praise the STR's combination of storage and stability. The battery tubes are genuinely water-resistant and provide convenient spare battery storage without adding external pouches. While heavier than minimalist options at 12.3 ounces, the STR delivers exceptional value for shooters running battery-powered optics and lights who want storage integrated into the stock itself. The enhanced cheek weld provides excellent support for consistent optic alignment.
