Magpul MOE SL™ Hand Guard, Mid-Length – AR15/M4

The MOE SL Hand Guard for AR15/M4 firearms with mid-length gas system and A2 font 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 accessories for mounting tactical lights, slings, grips, etc. Reinforced, heat-resistant polymer construction provides 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 gas block assembly and maximizes useable hand guard length. 


  • Narrow design replaces factory 2-piece, mid-length 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
  • Integral riveted aluminum heat shield
  • Front lip and long side extensions shields hand from hot sight assembly


  • Weight: 8.3 oz.
  • Length, maximum: 10.9 in.
  • Width, maximum: 1.8 in.
  • Height: 2.4 in.

*NOTE: The Mid-Length MOE SL Hand Guard is a direct replacement for most factory plastic, two-piece, mid-length hand guards and utilizes the existing ROUND front hand guard retaining cap and spring-loaded delta ring. Must be used with A2 front sight assembly; triangular retaining caps and other gas blocks are not compatible 

If so equipped, the factory sling swivel must be removed from the A2 front sight assembly. 

Made in U.S.A.

    I ordered this hand guard about a year ago here at SKD Tactical. I have put it through its paces, and once again Magpul does not disappoint. This thing has held up to some hard use and training. This is a great add to any Mid-Length Carbine Riffle. This thing offers plenty of space to mount M-Lok compatible items as far forward as you want on the hand guard, and the slimmer profile makes it fit the hand much better. Don't get me wrong the original MOE hand guard was great, but just a little bulky for my fat hands to get a good solid grip that was comfortable. All in all i highly recommend this product. HINTS: You will need to remove the front sling swivel. Also, when installing this drop-in hand guard do your self a favor and remove any optics you have on the gun that stick out farther than the upper receiver as the hand guard covers part of the delta ring and the optic will get in the way, preventing a easy installation.
