The Magpul STR is a feature-rich modification of the popular CTR series, designed to replace the standard buttstock on AR-15 / M4 platform carbines. It combines a lightweight, reinforced A-frame design with an improved cheek weld and two functional storage compartments for essential gear.

If you are looking for maximum cheek-weld comfort, a wobble-free fit, and a convenient place to store spare batteries on your rifle, the Magpul STR is the ideal upgrade.

Key Features and Benefits:

• Enhanced Cheek Weld: The sloped, widened cheek weld provides a comfortable, anatomically correct surface for improved sight alignment without creating an overly bulky profile.

• Water-Resistant Battery Compartments: Features two sealed storage tubes with rubber plugs located on either side. Each compartment holds up to two CR123A or AA batteries, accessible from the rear in any stock position.

• Friction Lock System: A supplemental friction lock minimizes play on the receiver extension tube, significantly improving stability and shooting accuracy.

• Ergonomic and Durable Design: The reinforced polymer A-frame protects the release latch from accidental activation while keeping weight to a minimum.

• Anti-Slip Rubber Butt-Pad: Includes a replaceable 0.30" (0.76 cm) rubber butt-pad that ensures a firm shoulder grip—even with body armor—and helps mitigate felt recoil.

• Versatile Sling Attachment Options:

  • Rear Type 1 push-button QD swivel socket for up to 1.5" swivels (swivel sold separately).

  • 1.25" sling loops integrated into the bottom and rear of the stock.

• Broad Compatibility: Fully compatible with Magpul ASAP®, ASAP® QD, and other receiver-mounted sling attachments.
