The Magpul STR Carbine Stock delivers enhanced stability and customization for AR-15 platform rifles through its innovative dual-side storage system and adjustable cheek riser. This mil-spec compatible stock transforms standard carbine setups into precision-oriented configurations.

What Makes This Different

Unlike basic collapsible stocks, the STR features dual waterproof battery storage compartments and an adjustable cheek riser for consistent scope alignment. The friction lock system eliminates buffer tube wobble that plagues standard mil-spec stocks. Storage compartments accommodate CR123, AA, or N-cell batteries while maintaining the stock's structural integrity.

Key Features

  • Dual waterproof storage compartments with friction-fit caps
  • Adjustable cheek riser with 0.25-inch height adjustment
  • Friction lock eliminates mil-spec buffer tube play
  • QD sling swivel socket compatible with push-button swivels
  • Stealth Gray finish matches Magpul furniture systems
  • Reinforced polymer construction with steel hardware
  • Six-position length of pull adjustment (3.25-inch range)
The STR excels in precision shooting applications where consistent cheek weld matters. Competition shooters benefit from the repeatable scope alignment, while tactical users appreciate the onboard battery storage for optics and accessories. The friction lock system maintains zero-shift performance during rapid position changes. Weather-sealed storage compartments protect batteries in adverse conditions.
