Product Description

The Magpul CTR (Compact/Type Restricted – Military Model) is a drop-in replacement butt stock for carbines using mil-spec receiver extension tubes. 

Designed for light, fast action the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation. The extra-power lock mechanism uses a premium chrome-silicon spring to avert auto-collapse failure and maintains strength by resisting spring relaxation. 

The CTR also features a supplemental friction lock system that eliminates wobble for enhanced weapon stability and accuracy. The Military Model includes a standard 0.30” rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.

Note: There are two basic types of M4 Carbine Receiver Extensions (buffer tubes): Mil-Spec and Commercial. If you have a Commercial extension on your rifle, make sure to order the Commercial CTR (MPMAG311). If you have one of the uncommon military tubes with an extended slant-back, please contact Magpul for an Extended 0.55” Rubber Butt-Pad (sold separately).  Made in the USA.

CTR Stock Install Instructions

Step 1:  Remove Existing Stock

Remove existing stock per armory guidelines. Refer to US Army TM 9-1005-319-23&P for assistance.

Step 2: Install CTR Stock

DO NOT FORCE PARTS TOGETHER!! Align the stock body with the carbine receiver extension and gently slide together until the stock stops (approx. 2-1/8”). Depress release latch with one hand. With the other hand, grasp both ends of release pin and pull down firmly. Push stock forward to mount.

NOTE: If stock does not easily slide over receiver extension, refer to fit guide on box.

Step 3: Friction Lock Test

With the stock installed and secured in position, depress the friction lock to minimize movement.

NOTE: Friction Lock performance may vary depending on exact receiver extension size.

Step 4: Verify Install

Perform final inspection including function test per US Army TM 9-1005-319-23&P Unit and Direct Support Maintenance Manual to verify correct installation. If you experience any issues during installation, please refer to the “Related Info” tab, located on the product page at www.magpul.com. Always test fire your weapon before using it in an operational environment.

                CTR Stock Adjustment Instructions

Extend/Collapse Stock

Fully depress the release latch and pull the stock rearward to extend or push stock forward to collapse. Intermediate positions may be selected by depressing the release latch and moving the stock back to the desired position. When desired position is found re-engage friction lock bolt for best results.

 

Remove Rubber Butt Pad

Use a 1/8” hex key to remove the two butt pad screws. Using a bullet tip or flat head screwdriver, depress the two top snap hooks to release the pad. Install optional polymer Carbine Butt Cap if desired.

WARNING: The CTR commercial model has an extended .55” rubber butt pad to accommodate extended-length receiver extensions (buffer tubes). Removal of the butt pad is not recommended since the extension tube may protrude past the end of the stock in the fully collapsed position and may cause discomfort or injury during use.
