KAK Industry 4" AR15 MLOK Free Float Handguard

Designed and machined here in the U.S.A., KAK's free float AR15 handguards are of exceptional value.   

Our twin lug fastening system pulls the handguard firmly against the barrel nut, eliminating handguard deflection, while the anti-rotation tabs guarantee that the handguard is in perfect alignment with your upper receiver.  Unlike the pressure clamps used on many handguards, our mounting system ensures that your handguard will not detach from the upper or rotate out of place. Our Handguard design is incredibly rigid in combination with our HD barrel nut and heavy-duty mounting hardware.

    Exceptional For 3 Reasons

    Three things I like about this. Material qualities are excellent. The alignment tabs and locking mechanism for the barrel nut are as good or better than I've ever used. Last, with a C clamp hold across the handguard to magwell area, the bottom area that houses the barrel nut locking parts is perfect to lock down the C clamp, almost like a built in hand stop.
