Magpul MOE SL AR15/M4 Carbine Handguard FDE MAG538FDE

Forget the bulky, slippery feel of your standard handguard. Imagine a front end that feels like a natural extension of your arm—slim, lightweight, and perfectly textured for a rock-solid grip when it matters most. The Magpul MOE SL AR-15/M4 Carbine Handguard in Flat Dark Earth transforms your rifle’s handling profile, giving you modern ergonomics and M-LOK versatility without a complicated build. It’s not just a part; it’s the upgrade that makes your rifle behave the way you want it to.

The MOE SL was designed to answer a simple question: how do you give shooters a better, more confident interface with their rifle while keeping installation and cost straightforward? The result is a slim 1.8" profile that reduces bulk and improves control, especially when you run the rifle hard or need to transition quickly. The reinforced, heat-resistant polymer body keeps weight low and durability high, while a riveted aluminum heat shield and smart protective lip guard your hands from hot gas blocks and A2 sight assemblies. And because it’s M-LOK ready at the 2, 6, and 10 o’clock positions, you can mount lights, grips, and rail sections only where you need them—keeping the front end snag-free and streamlined.

Technical highlights and installation details are organized below so you can see at a glance how this handguard will fit your build and your needs.
