Description
The Magpul MOE Carbine Stock in OD Green is the stock a lot of folks reach for when they want to ditch the basic M4 buttstock that came on their AR-15 and get something with better ergonomics and a cleaner look. It drops right onto any Mil-Spec sized carbine receiver extension tube, so if you're running a buffer tube from Colt, LMT, Ruger, S&W, SIG, or most other mainstream makers, this thing slides on and you're set. Made in the USA, it weighs in around 8 ounces and measures about 6.9 inches, so it keeps your build light without giving up durability.
What the MOE Carbine Stock Brings to Your Build
The streamlined A-frame profile is the star here. It keeps the stock from snagging on slings, gear, or the edge of a vehicle door when you're shouldering fast, and it tucks the release latch behind a shield so you won't accidentally collapse the stock mid-use. The sloping cheek weld gives you a comfortable, repeatable spot to rest your face, and the chrome-silicon lock spring keeps your length-of-pull adjustment locked down where you set it. LOP runs roughly 10.7 to 14 inches depending on your tube, which covers just about any body type or gear setup.
Sling Options and Cheek Riser Support on the MOE OD Green Stock
Magpul didn't skimp on attachment points. You get rear and bottom 1.25-inch sling loops plus a lanyard hole on the toe for paracord rigs, and it plays nice with Magpul ASAP, ASAP QD, and other receiver-mount sling attachments. The side mounting slots accept optional CTR Cheek Risers if you're running higher optics or need a taller weld, and those slots even work on non-AR platforms.
The included 0.30-inch rubber butt-pad gives you solid shoulder purchase so the stock doesn't slide around on body armor or a plate carrier. This is a proven, no-frills upgrade that punches well above its weight, and the OD Green finish is a great match if your build is leaning toward an earthy or classic military look.

Frequently Asked Questions
Will the Magpul MOE Carbine Stock fit my buffer tube?
This is the Mil-Spec version, so it fits standard Mil-Spec diameter carbine receiver extension tubes, which is what most AR-15s ship with from makers like Colt, LMT, Ruger, S&W, and SIG. If your rifle has a Commercial-Spec tube instead, you'll want the Commercial-Spec model (MAG401), since the two diameters are not interchangeable. An easy way to check is that Mil-Spec tubes measure about 1.146 inches at the back where the stock rides.
Does the MOE Carbine Stock come with a buffer tube or hardware?
No, this is the stock body only. It's designed as a drop-in replacement that slides onto your existing Mil-Spec receiver extension, so you'll reuse the buffer tube, buffer, spring, and castle nut already on your lower. Installation is quick and doesn't require any special tools.
Can I add a cheek riser to the MOE OD Green stock?
Yes. The side mounting slots are built to accept Magpul's optional CTR Cheek Risers, which is handy if you're running taller optics or want a better cheek weld with the stock fully extended. Those slots also work on some non-AR platforms if you're getting creative with a build.
How does the MOE Carbine Stock compare to the CTR?
The MOE offers a lot of the same snag-free, lightweight feel as the CTR but in a simpler, more budget-friendly package. The CTR adds a friction lock to reduce wobble and a slightly beefier build, while the MOE keeps things straightforward and lighter. For a no-frills range or duty build, the MOE covers the bases well.
