  1. Fantastic
    Magpul again delivers perfect fit and finish with the SL hand guard. No wobble at all compared to the stock M4 hand guard. The added forward grip surface over the gas block in very nice. Once you remove the forward sling mount under the bayonet lug installation is pretty easy, just pull the delta ring back and drop it in, one half at a time. Love the M-LOK slots, added a sling mount and a light mount rail.

  2. Best choice for a drop in Handguard
    Went with the Stealth Gray and it looks awesome! The heat shield works as advertised VS free float handguard. Magpul makes some of the best stuff at any price and why anyone would buy the airsoft or Chinese knockoff is beyond me...

  3. Great Product
    Magpul has plastic down to a science.
    The fit is perfect. Installation is easy.
    And it looks great.
    You don't always need a $400 rail on your Rifle.
    Amusing point by Albert - Airsoft and Chinese.
    I hope he knows Magpul has a factory in China making their Airsoft brand...ahem...

From CA$51.47 Regular Price CA$51.47

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

A large front extension and lower lip protects the user from the hot front sight assembly and maximizes useable hand guard length.
