See it built on instagram

  • Backed by our Swarm Lifetime Warranty

    1. Relentlessly tested and built to last. Aggressive angled dual purpose cutouts were specifically tested and implemented to reduce the most weight possible, while still maintaining maximum strength and structural integrity. The result is an extremely lightweight design that can withstand and excel during any mission under the toughest conditions.
    2. Solid as a rock. Our unique anti-slide plate feature solves the biggest problem that plagues handguards today - unwanted sliding. By engineering a 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 required.
    3. Quick and simple installation. Intentionally engineered to be the easiest handguard to install on the market. Save time and prevent frustration with the simple non-barrel nut timing design.
    4. Don't pay ridiculous retail markups. No absurd markups, no middleman, no nonsense. Just a handguard direct from us to you.

    The shipping was relatively fast, free. The fit was very close, the finish had one blemish but not obvious enough to ding it a full star. It looks awesome and I’m excited to shoot it this spring and see how the accuracy is effected at range. It is lighter than the stock furniture and sight that came with my ar. I looked at many rails and this rail was the best for my situation. Easy installation, directions included. Great rail, good price, Thank you STYNGR for making this quality rail affordable.

    1st AR15...

    The stinger rail is top notch and in my opinion better than most even more expensive rails. Everything you need in the box even the wrench adapter. Well thought out rail system and I’ll be purchasing more in the future

    15” HWK-...

    Posted by Robert Levonyak on Jan 15th 2019

    Very nice handguard. Looks bad a** on my .223 build. Only think I noticed is where the anodizing was knicked in two spots, but that was probably done during the anodizing process. Touched it up with some aluminum black and it’s good to go. Will be purchasing more STNGR products in the future! Do not hesitate to buy yours today. Very durable and lightweight. Thank you STNGR

    The quality of this hand guard far exceeds its cost. The fit and finish is perfect. Great to see that American made can still be affordable without sacrificing great craftsmanship.
