Description
The Magpul Industries MOE Carbine Stock (model MAG400) is the Mil-Spec variant of Magpul’s flagship drop-in buttstock, purpose-built as a direct replacement for the standard carbine stock on AR-15, M16, and M4 carbines using a mil-spec sized receiver extension tube. The stock body is molded from polymer in a low-glare Stealth Gray finish, keeping weight to a minimum while delivering the snag-free profile and fast, one-handed adjustability the MOE line is known for.
Adjustment is handled by a familiar bottom-mounted lever latch that locks into one of 6 positions for a Length of Pull range of 10.50″ to 13.80″, giving a comfortable, repeatable fit for a wide range of shooters and shooting positions. The rear face is fitted with a removable 0.30″ rubber butt-pad that helps keep the stock planted on the shoulder during recoil and can be swapped or replaced as needed.
This listing is for the stock body only; the Mil-Spec receiver extension tube is not included and must be sourced separately if you are building from a bare lower. Designed and made in the USA, the MOE Carbine Stock is a straightforward, no-nonsense upgrade for any Mil-Spec tube carbine.
