Magpul STR Carbine Stock Mil-Spec for AR15/M4

CTR stability plus onboard storage — the STR is the carbine stock for shooters who want everything locked down.

The Magpul STR (Storage/Type Restricted, MAG470) starts with the CTR's celebrated friction-lock system — clamping the stock rigid against the receiver extension for zero wobble — then adds a wider cheek weld and two water-resistant battery storage tubes in the butt. Optic batteries, spare parts and small essentials ride in the rifle itself, protected from the weather and always where you left them.

The broader body also deepens the cheek weld surface, giving a fuller, more supportive reference for precision work behind magnified glass. A rubber buttpad, ambidextrous sling options and QD compatibility complete a stock that turns up on duty and competition rifles alike.

Why shooters choose the STR

• Dual friction-lock system — fixed-stock rigidity, zero rattle
• Two water-resistant storage tubes — batteries and spares onboard
• Wider, deeper cheek weld — superb behind optics
• Rubber buttpad & QD sling integration — fully equipped out of the box
• Four finishes — Black, Flat Dark Earth, Olive Drab Green, Stealth Gray
