Magpul MOE M-LOK Carbine-Length Hand Guard - AR15 / M4 (Color: Flat Dark Earth)

"Fit right on my M4 no problem and feels very sturdy. Just be aware if you are getting this for a front wired gun the battery space is very tight and you will have to remove the heat shield.

"GET. THIS. FOR. YOUR. KWA LM4!!!!!!

Pros:

Spaces for M-Lock rails

Good lookin

Well Built

Light

Cons:

Polymer


Overall, I would reccomend this to everone.

"This is one of the Best Hand Guards on the Market it may not fit all Batteries but i just taped mine on the outside and it worked just ass good!! I Really Recommend This For the KWA KM4A1 Because the Gun is Kinda A Heavy Gun and this And The Vertical Grip Is the Best Out There!!! Really Recommend

"Bets handguard my only con is that it is tight to get in. Looks really nice though. Definitely should buy!
