KAK Industry AR15 13" 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.

  • Hard coat anodized

    KAK 13" M-Lok Handguard

    Posted by Mike on December 12, 2023

    I recently purchased the 13" version of this hand guard for my 6.5 Grendel and I am very impressed, especially considering the price. The fit and finish is excellent and installation was very simple, with all necessary hardware and barrel nut wrench included. The way it attaches with the two locking blocks makes for a rock solid lock up and there is very little flex in the handguard. Overall a great product and probably my go to handguard for future builds.

    KAK MLOK Handguard 13"

    Posted by Jeffrey Mitchell on December 11, 2023

    I currently own Geissele, Daniel Defense, Knights, Aero Precision, Midwest Industries handguards, of many different sizes. I can honestly say that I will be using the KAK handguards for the custom rifles I build for my "operating" clients as well as for my self! Equal to the super high end brands! Completely straight, very tight fit, very solid....and NOT $275.00 plus in price!!!

    This is my second KAK hand guard. Solid company with great products. Smooth outside, great anodizing. Strong construction. M-loc on 7 sides. Endless mounting options. This one is going on my spr 18” .. I also have their 9” hg. Great for my takedown 5.56… 11.5” build.

    13” handguard

    Very lightweight and strong handguard, looks clean and it’s pretty thin. One of the few great 13” options I would recommend on a 13.7/13.9” build.

    Solid As They Come

    I am beyond impressed with KAK's quality and products. I have nothing but good things to say about this rail, from its fit and finish to how it feels when running and gunning. This rail is an excellent addition to any build and the price is unmatched! I have some other "Gucci" rails on my other rifles and after using this on a most recent build I'm questioning why I even bothered spending 3X the price on other brands. Seriously, KAK you make excellent parts and I will be a customer for life.

    Very happy with my purchase. Handguard is super solid. The wedge lock design is great and holds tight. I had to remove my handguard to get my barrel pinned and welded and it took some work to get the wedges back out. I like that. It’s super solid and a great value. Only handguard I’ll use from now on.

    Solid hand guard at a great price

    Posted by mezcalfud on February 8, 2023

    My hand guard savvy is a few years behind so I set out looking for a better locking system and MLOK. I found this and the price was right and I am impressed. Rail itself is solid and the locking system is so much better than indexing/shims/pinch fit. The wrench was nice too. Thanks!

    Very nice handguard

    Posted by Bs on August 29, 2022

    The handguard has 2 beveled wedges that bolt together with Allen bolts & the barrel nut have groves that the bolts go through & the fit was great & it feels good no sharp edges. Thanks
