Magpul Original Equipment (MOE) is a line of firearm accessories designed to provide a high-quality, economical alternative to standard weapon parts. The MOE line distinguishes itself with a simplified feature set, but maintains magpul engineering and material quality.

The Magpul MOE stock is a drop-in replacement butt-stuck for carbines using commercial/military 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 military model includes a standard .30" rubber butt-pad, while the commercial model includes an extended .55" rubber butt-pad to accommodate longer slant-back extension tubes.

The patent-pending Magpul CTR (Compact / Type Restricted) is a drop-in replacement butt stock for carbines using commercial or military-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 .30" rubber butt-pad, while the commercial model includes an extended .55" rubber butt-pad to accommodate longer slant-back extension tubes.

* Friction lock performance may vary depending on the receiver extension's dimensional tolerances.

The ACS (Adaptable Carbine/Storage) is a drop-in replacement for the standard M4 stock body, offering an integral storage compartment, removable battery tubes, and a friction locking system to eliminate all stock movement.

* Friction lock performance may vary depending on the receiver extension's dimensional tolerances.

The Magpul UBR (Utility/Battle Rifle), U.S. Patent 6651371, is a fully-featured, adjustable butt stock for the AR15/M16. Unlike typical collapsing stocks, this modular design offers the stability of a fixed stock with consistent cheek weld in any position. Seven-position length-of-pull (LOP) adjustment is quickly executed with gross motor movement while the integral preset system allows direct access to a preferred position. A robust lock mechanism and multi-shell construction increase durability under severe impact conditions experienced during malfunction clearing and accommodates large-bore AR calibers. The UBR also provides extra counterbalance weight to improve handling on full-length rifles and weapons with muzzle-heavy accessories or grenade launchers. Optional components such as dual-side sling mounts and metal strike plate allow the UBR to adapt to the mission at hand.

Note: The UBR includes the necessary Entry Receiver Extension tube and all mounting hardware. An M4 Carbine Buffer and Spring are required for use with the UBR and are not included.

The Magpul PRS (Precision Rifle/Sniper) is a drop-in, precision-adjustable butt stock for rifles with A1/A2 fixed stocks. Designed to offer the fine-tuned, customized feel of a precision stock, the PRS is adjustable for both cheek riser height and length-of-pull without sacrificing the durability necessary to withstand the operational environment. Compared to the A2 stock, the PRS can shorten the LOP by 0.25in or extend it by 0.75in. Machined aluminum adjustment knobs feature positive-locking click detents to maintain position under recoil and allows easy, tool-less adjustments by simply rotating the knobs. Machined aluminum butt-plate and alloy steel adjustment shaft provide stability and strength to withstand severe impact conditions. Rubber butt-pad offers positive shoulder purchase to prevent slippage for optimal accuracy even with body armor or modular gear. Bottom Picatinny-type rail allows for monopod use, additional sling mounts or storage. Stock includes all mounting hardware for A1/At type rifles with fixed stock.

Note: the PRS requires a Rifle Receiver Extension tube, Rifle Buffer and Spring (Not included).

Note: THE AR15/M16 MODEL IS NOT TO BE USED ON AR10-TYPE RIFLES. Due to Charging handle clearance issues, the stock is not compatible, and only the AR10/SR25 model stock should be used. However, the AR10/SR25 model stock may be used on AR15/M16 rifles to provide additional charging handle clearance.

Fits any HK variant that has a factory fixed-stock steel backplate and standard buffer (not included). Installs easily with included hardware. NOT compatible with the HK heavy buffer. Compatible models include: HK91, HK93, HKG3, HK33, PTR91, SR9. Will fit Cetme backplates with some gunsmithing.

Adjustable for cheek weld height, length of pull, and cheek weld placement, the Precision Rifle/Sniper (PRS) stock offers adjustability in a drop-in form for the FAL metric pattern rifle, while still utilizing the factory standard buffer unit.

Fits any METRIC lower trigger frame with standard spring guide tube. Installs with screws from standard buttstock (not included).

Will not fit INCH or PARA lowers. A FAL-type buttstock removal tool is recommended for easy installation.
