The MOE SL Hand Guard for AR15/M4 firearms with carbine-length gas system and A2 front sight* provides modular flexibility with M-LOK accessory slots in a lightweight, sleek, cost effective design.

Designed with versatility in mind, M-LOK slots at the two, six, and ten o’clock positions allow the attachment of optional Picatinny rail sections and other direct-attach M-LOK accessories for the mounting of tactical lights, slings, grips, etc.

Reinforced, heat-resistant polymer construction provides operational durability without the weight and expense of an aluminum rail hand guard. A large front extension and lower lip protects the user from the hot front sight assembly and maximizes useable hand guard length.

Made in U.S.A.


  • Narrow design replaces bulky M4 Carbine-type plastic hand guards
  • Easy to install utilizing existing delta ring and round front hand guard retaining cap with A2 front sight assembly*
  • Slots at the two, six, and ten o’clock positions for mounting direct-attach M-LOK accessories or M-LOK 1913 Picatinny rail sections
  • Reinforced, heat-resistant polymer construction

  • Front lip and long side extensions shields hand from hot sight assembly

NOTE: The MOE SL Hand Guard – Carbine-Length is a direct replacement for M4 Carbine-type plastic, two-piece hand guards and utilizes the existing round front hand guard retaining cap and spring-loaded delta ring.

*Must be used with the triangular A2 front sight assembly with round retaining cap; other gas blocks are not compatible. Factory sling swivel is not compatible and, if equipped, must be removed from the A2 front sight assembly.

looks awesome on my m&p sport 2. very pleased with this purchase and will be ordering from at3 in the future.

Great Handguard for A2 Sights and Railed Gas Blocks

I was agonizing over how best to upgrade my DPMS Oracle; It has a funky low-profile railed gas block, and the big clunky quad rail I'd put on before was just not working for me. This handguard transformed my AR - it's way more comfortable to shoot now, and looks a lot better than it did before! Would definitely recommend for someone wanting a clean, sleek, and simple look to their rifle, especially those with A2 sights or railed gas blocks. You can add attachments using the MLok slots but I like it just the way it is. Magpul engineered it to be a tight fit, so be prepared for some elbowgrease getting it on there. Looks awesome when paired with either the Magpul MOE or MFT Minimalist stock.

Thanks for sharing your feedback, Brad. We're glad you're satisfied with your purchase. Cheers!
Handguard to dye for

Pleased with the sand colored hand guard and magazines I have. They take Rit dye well to make the 300 AAC mags and upper obvious.
Service from AT3Tactical was fast and easy.

Thanks for sharing your feedback, William. We're glad you're satisfied with your purchase. Cheers!
Nice hardware

The slim line and extra length from the Magpul handguard are a must. Well made. The OD Green color is awesome.
