The MOE M-LOK Hand Guard Mid length Gray is a drop-in polymer handguard designed for AR-15 rifles with mid-length gas systems. It provides M-LOK accessory slots for lights, grips, and rail sections without adding the bulk or weight of a full-length rail system.
This handguard replaces standard two-piece plastic guards on carbine-stock rifles. The gray finish matches receivers and furniture that use gray or stealth-gray anodizing or coatings.
Mid-length handguards suit builds where the gas block sits farther forward than a carbine-length system but shorter than rifle-length. They offer more forend space for hand placement and typically improve recoil impulse smoothness.
Key Facts
Product Name: MOE M-LOK Hand Guard Mid length Gray
SKU: Mag426-Gry
Finish: Grey
Categories: Handguards & Forends, Parts
Mid Length Handguard Fit and Gas System Compatibility
Mid-length gas systems measure approximately nine inches from the receiver face to the gas port. This handguard is sized to cover that gas tube and stop just behind the front sight base or low-profile gas block. It does not fit carbine-length or rifle-length gas systems without leaving gaps or running too long.
Confirm your gas system length before ordering. Measure from the upper receiver to the gas block, or check your barrel specification. If you are unsure, call 817-393-4000 and our gunsmiths can help identify what you have.
M-LOK Slots and Accessory Mounting
M-LOK is a negative-space mounting system that uses slots machined into the handguard. Accessories attach with small T-nuts that slide into the slot and lock tight with screws. The system saves weight compared to continuous Picatinny rails and keeps the forend slimmer when no accessories are mounted.
Common M-LOK accessories include vertical grips, hand stops, light mounts, and short rail sections for bipods or sling mounts. You control where each component sits along the handguard slots, which lets you tailor the setup to your grip and shooting position.
Drop-In Installation and Carbine-Stock Compatibility
Drop-in handguards clamp around the barrel nut with a delta ring or similar retaining system. They do not require you to remove the muzzle device or gas block. Installation takes minutes with basic tools.
This handguard is designed to fit carbine-length buffer tube and stock assemblies. If you are building or upgrading an AR with a mid-length gas system and a collapsible stock, this handguard will mount directly. Rifle-length stocks or A2-style fixed stocks may interfere; confirm fitment if you run anything other than a standard carbine receiver extension.

Frequently Asked Questions
Q: Does the MOE M-LOK mid-length handguard fit carbine-length gas systems?
A: No, this handguard is sized for mid-length gas systems only. Carbine-length gas systems are shorter and will leave a gap between the handguard and the gas block. Mid-length gas systems place the gas port about nine inches from the receiver; this handguard matches that spacing.
Q: Can I mount a Picatinny rail section to the M-LOK slots on this handguard?
A: Yes, M-LOK rail sections attach directly to the slots using M-LOK hardware. The rail section locks into the slot with small T-nuts and screws, giving you a Picatinny surface wherever you need to mount an accessory that requires a 1913 rail interface.
Q: What tools do I need to install a drop-in mid-length handguard?
A: Most drop-in handguards require a handguard removal tool or a simple clamp to compress the delta ring, then the two halves slide over the barrel nut. No armorer’s wrench or barrel removal is needed. If you have questions about your specific upper receiver, call 817-393-4000 and we can walk you through it.
Q: Will the gray finish on this handguard match my receiver color?
A: Gray finishes vary slightly between manufacturers and batches, so an exact match is not guaranteed. The gray finish on this handguard is designed to complement gray-anodized receivers and furniture, but lighting and wear will affect appearance. If color matching is critical, call 817-393-4000 to discuss your build.
Q: How much forend space does a mid-length handguard give compared to carbine length?
A: Mid-length handguards extend roughly two inches farther forward than carbine-length guards, giving you more room for hand placement and a longer sight radius if you use iron sights. This extra length also moves your support hand farther from the muzzle, which some shooters find more comfortable and better balanced.
Q: Can Western Sport help me choose the right handguard for my AR build?
A: Yes, our gunsmiths work with AR builds daily and can answer fitment, gas system, and compatibility questions. Call 817-393-4000 and describe your upper receiver, gas system, and intended use, and we will recommend the handguard that fits your setup.
