HWK M-Lok Free Float Handguard 13.5" - AR15/M4

  • Backed by our Swarm Lifetime Warranty

    1. Extremely versatile. The HWK’s signature front cut serves an important role in weight reduction and overall function of the system as a whole. Weight savings provided from the cut allowed us to implement the dual purpose picatinny rail section at the bottom with minimal weight gain. The result is enhanced functionality and performance, while still yielding you an incredibly lightweight construction.  
    2. Meticulously engineered for functionality. The unique bottom 1913 picatinny rail was deliberately integrated to act as both an attachment point for mission specific accessories, as well as a natural handstop when firing. The angled rear construction creates an ergonomic grip to achieve the perfect hand placement every time. You also prevent the dangerous risk of accidentally overreaching and exposing your hand to the scorching barrel or explosive muzzle blast. 
    3. Effortless install. Over-engineering makes simple problems unnecessarily complex. With that guiding principle in mind we set out to, and effectively succeeded in developing the simplest installation process on the market. Absolutely no barrel nut timing required. The system developed also solves the biggest problem faced by handguards today – unwanted slipping. By engineering an anti-slide plate that locks the handguard to the barrel nut, your handguard physically won’t be able to slide off no matter how hard you run it. No Loctite needed.

Awsome Rail!

Awsome rail and can’t beat that price!

.277 Wolverine Build Complete

I can't express enough how pleased I am with my STNGR HWK M-LOK Handguard. The fit and finish are superb. The anti torsional tangs and Anti-slide Plate are design features I was very impressed with, knowing that many other handguards don't have these features. The barrel nut was great quality and has wider flats on it to accommodate a standard crow's foot. The Installation Guide is easy to follow with better than average as you go illustrations. For the quality and design features one would expect to pay more but not with STNGR the price is very reasonable. All this and made in the USA. Keep up the great work STNGR and I definitely plan on doing business again with you.

Hawk MLock 13.5

It’s really nice. Excellent craftsmanship. I would recommend it to all my friends as it was recommended to me. I can’t wait to finish this project and fire some rounds!


I am very happy with the fit and finish of the handguard, it looks great. Delivery process was great and all for a fantastic price.

Not Top Class

Looks (shape) & fit are great. Was not impressed with the finish. It is real grainy looking & the color is off compared to the receivers.

Hawk hand guard

Easy to install, no timing needed. Looks great on my AR. I will buying another. Quality materials

Very nice looking item, smoothed edges, Magpul front sight fit well and the quick disconnect in the back for the sling doesn't allow the sling loop to rotate more than +- approx 10 degrees, Nice not rotating 360 and getting the sling all twisted. The front quick disconnect hole however doesn't have that feature and is thinner and the quick disconnect flops in that hole in and out as there isn't much meat on that hole. It is just a hole, no cut aways for the ball bearings to sit in like the back one. Maybe get one of those top rail QD !!

Too easy

Install went smooth, fitment and performance where spot on, no problem
