Magpul CTR Carbine Stock Mil-Spec for AR15/M4

The carbine stock that professionals default to — the CTR kills wobble and gives you the same cheek weld every single time.

The Magpul CTR (Compact/Type Restricted, MAG310) is built around one mechanical idea executed perfectly: a supplemental friction lock that clamps the stock body hard against the receiver extension, eliminating the rattle and play that plague standard collapsible stocks. The result is a rock-solid cheek weld that behaves like a fixed stock, from a unit that still adjusts instantly across the buffer tube's positions.

The A-frame profile sheds weight and snags, the rubber buttpad locks into the shoulder, and sling integration is comprehensive — including a standard QD socket point. It is the stock you see on duty rifles and serious training carbines for a simple reason: it removes variables, and consistent shooting is built on removed variables.

Why shooters choose the CTR

• Supplemental friction lock — zero wobble, fixed-stock stability
• Repeatable cheek weld — the same sight picture every mount
• Slim A-frame profile — light, snag-free, fast handling
• Rubber buttpad — plants in the shoulder pocket, protects the stock
• Three finishes — Black, Flat Dark Earth, Olive Drab Green
