MOE Commercial Carbine Stock MAG401

MOE™ M4 Carbine Collapsible Butt-Stock – Commercial

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 – Model is a drop-in replacement butt-stock for  AR-15 carbines (Select MAG400 FOR MILSPEC 1.14"DIAMETER TUBES OR MAG401 FOR COMMERCIAL 1.17" DIAMETER 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. BOTH Models include an extended 0.55” rubber butt-pad to provide positive shoulder purchase and accommodates longer slant-back extension tubes.


Note: There are two basic types of M4 Carbine Receiver Extensions (buffer tubes): Mil-Spec and Commercial.
