Description

The Magpul MOE SL-M is a lightweight mil-spec carbine stock for AR-15 and M4 rifles, fitting any Mil-Spec-diameter receiver extension.

The lightest stock in the Slim Line family — the MOE SL-M strips the concept to its fighting weight.

The Magpul MOE SL-M Carbine Stock (MAG1242) is for builders who count grams. It takes the SL family's snag-free geometry, angled rubber buttpad and forward ambidextrous sling mounts, then minimises material everywhere strength allows — producing the slimmest, lightest MOE SL variant Magpul makes. On a lightweight build where every component is chosen deliberately, the SL-M is the stock that completes the maths.

Nothing essential is sacrificed: the cheek weld remains comfortable and repeatable, the release lever stays shielded against accidental adjustment, and the reinforced polymer construction carries the same durability as its heavier siblings.

Why shooters choose the MOE SL-M

  • Lightest MOE SL stock made — built for true lightweight builds
  • Slim, snag-free profile — nothing to catch on kit or cover
  • Forward ambidextrous sling mounts — clean two-point rigging
  • Angled rubber buttpad — fast, positive shoulder mounts
  • Three finishes — Black, Flat Dark Earth, Olive Drab Green

What the MOE SL-M fits

Fits AR-15/M4 rifles with a Mil-Spec-diameter carbine receiver extension (buffer tube) — the same interface as the rest of the MOE SL family. Commercial-diameter tubes are larger and will not take it, so check yours before ordering. Installation is the usual tool-free slide-on swap.

Tracking details are emailed on dispatch. UK delivery only.

Returns

You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging.

FAQ
Will the SL-M fit my carbine?

It fits AR-15/M4 rifles with a Mil-Spec-diameter carbine receiver extension, the same interface as the rest of the MOE SL family. Commercial-diameter tubes are larger and won't take it, so check yours before ordering. Fitting is an ordinary stock swap on the tube.

What's the point of the SL-M in the range?

It's the lightest stock in the MOE SL series, so it's the one to pick when you're trimming weight off a build rather than adding features. You give up the storage compartment of the SL-S to get there. If your rifle is already front-heavy, saving weight behind the receiver is a sensible place to start.

How does it take a sling?

It has forward ambidextrous sling mounts, so you can run the sling on either side without changing hardware. Mounting the sling forward on the stock keeps it closer to the receiver and out from under the shoulder. Check what your chosen sling's rear attachment needs before ordering.

Which colour, and how does it compare with the SL-S?

Black, Flat Dark Earth and Olive Drab Green are offered. Go for the <a href="/products/magpul-moe-sl-s-carbine-stock-mil-spec-ar15-m4">MOE SL-S</a> if you want the enclosed storage compartment and QD sockets, or stay with the SL-M if light and simple is the priority. Both are listed in <a href="/collections/magpul-ar-15-stocks">Magpul AR-15 stocks</a>.

What about shipping?

Stocks leave the United Kingdom with £5 tracked UK delivery in 7–10 business days, and tracking is emailed when the order ships. If a part turns out to be the wrong fit, see our returns policy or <a href="/pages/contact">contact us</a> and we'll help sort it.

7 to 10 business days from the date of your order. Every order is sent Royal Mail Tracked for a flat £5 and you receive tracking details by email when it is dispatched.

Is this a genuine manufacturer product?

Will it fit my rifle, shotgun or pistol?

Compatibility notes on this page come from the manufacturer. If you are unsure, email us with your make and model before ordering and we will check rather than guess.

Do you offer multi-buy discounts?
