Hardened Arms LumaShark AR15 Handguard | SHOT 2017

I always enjoy going up to the NEXT booths at SHOT (which is the place where all of the vendors that are either new or on a waiting list to get a floor booth are staged). Most attendees of the show spend their time on the main floors and never get the chance to see some of the products.

This time I found Hardened Arms, a company that actually had something I had never seen before, and I found interesting enough to share with you readers. One of the thing we can all agree is that the industry around AR platformed rifles has given us no end of things to hang from our handguards–arguably some of them more useful than others. Lights and lasers probably being the most useful category. The problem is that they are mounted to adjustable systems with screws and other hardware and sometimes those things get loose (if you are not super religious about checking them).

Integral tubes on the rail allow for a variety of attachments.

Hardened Arms’ take on the problem is a trade off. They’ve engineered a 12″ free float rail from 6061-T6 aluminum with two forward tubes that can accommodate a number of accessories (1150 CREE lights at 500 lumens, infrared 940 NM bulbs, or a Laser). It is fairly lightweight at just under 20 ounces with installed CR123A batteries. Of course it has a standard top picatinny rail, and also supports the M-LOK standard on the sides and bottom. Internal diameter of 1.8″ will accommodate many suppressors.

It surprisingly was not awkward to hold, and should accommodate a number of grip styles for those that still rock the ole “C-Clamp”. I like the idea of having something that can’t get knocked loose, and there are even some advantages for barricade shooting (you can brace with one of the tubes and peek the barrel and other tube over to get some light on target. Definitely an innovative solution, and one that could potentially accommodate other accessories like “less-lethal” alternatives.

Prior to that he was a paramedic somewhere in DFW, also doing some Executive Protection work between shifts. Now that those exciting days are behind him, he has embraced his inner “Warrior Hippie” and assaults 14er in his sandals and beard, or engages in rucking adventure challenges while consuming craft beer. To fund these adventures, he writes medical software and builds websites and mobile apps. His latest venture is as one of the founders of IronSights.com; a search engine for all things gun related. He hopes that his posts will help you find solid gear that will survive whatever you can throw at it–he is known (in certain circles) for his curse…ahem, ability…to find the breaking point of anything.

    I was hoping it was a double barrel shotgun under there.


    I gave found that grips using the two Buttonhead screws x4 always ends up with one threaded hole on the barrel nut to be completely daft, or the threading to end up rubbish in one way or another.

    I have an older KAC rail that I returned for one of the holes on the barrel nut simply not being drilled in the right spot. (.7mm away from hole on grip.)

    My currente noveske rail’s buttonheads rust if you look at them funny, and the bolts seem to want to misthread by desighn. So frustrating despite loving the rail.

    A lack of modularity/adjustability seems like a step backward by several decades, but darned if that doesn’t look great and have a lot of potential for a CQB setup or truck/saddle gun.
