Great product and great customer service!! A++++++. Can't go wrong with this company!!!

This handguard is bad ass!!!!

The fit and finish is superb and I will be buying these for future builds as well. You guys should have a way people could upload their photos of their builds! This looks amazing on my pistol build!

Texas tough

Fits my hand like it was custom made. I had it and my heavier 10.5 slip out of my hand on a concrete floor. The STNGR hit first and the $180 10 in landed on it. Dented my 10 in and my stngr had a 5in scratch that wiped off. You owe me a 10” guard.

Top notch

The install was very easy I love the design of how it fits on to the rifle very sturdy as well. Most of all I got a sticker that's now on my truck window proud..don't matter what you buy no one gives you stickers, u could give up a kidney n still not get one So thanks again for providing me with an awesome addition to my rifle as well as the opportunity to help promote you guys


Not only do they look badass. They fit great. Easy install. I recently purchase 2 of the keymod hwk handguards. One was a 13.5" and the other a 15" . I put one on my ar15 and the other not sure. Was going to put on my psa pa10. Surprisingly the pa10 came with a descent mlok guard. Havent shot the ar with the 13.5 handguard on it yet. I am sure it will hold up great. High quality and looks even better. Thanks! Mike

Awesome handguard!!

Hawk hand guard

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

Fantastic product

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
