Sleek And Cost-Effective Replacement For Standard AR-15/M4 Handguard

The Magpul MOE Slim Line AR-15 Handguard – Mid Length is a sleek and lightweight replacement for standard AR-15/M4 Carbine-type plastic handguards with Mid-length gas systems and an A2 front sight*. A versatile and cost-effective option that offers modular flexibility of the M-LOK system for your rifle.

The Magpul MOE Slim Line AR-15 Handguard – Mid Length is designed for versatility in AR15/M4 platforms. The M-LOK slots at the two, six, and ten o’clock positions offer more flexibility that allows the attachment of optional 1913 Picatinny rail sections and other M-LOK accessories for direct mounting of tactical lights, slings, grips, etc.

Provides Operational Durability With Less Weight

The MOE SL Hand Guard is designed from reinforced, heat-resistant polymer that provides operational durability without the weight and expense of an aluminum rail handguard.

The large front extensions and lower lip provide additional protection for the operator from hot gas block or hot front sight assembly and maximize the use of the length of the handguard.

  • 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

NOTES:

  • The Mid-Length MOE SL Hand Guard is a direct replacement for most factory plastic, two-piece, mid-length hand guards and requires a ROUND front hand guard retaining cap and rear spring-loaded delta ring (some mid-length firearms are equipped with a triangular retaining cap and are not compatible). Not compatible with piston operated AR platforms.
  • *Must be used with the A2 front sight assembly as other gas blocks are not compatible. If so equipped, the factory sling swivel must be removed from the A2 front sight assembly.
