    1. Best of both worlds.  The RPTR is the perfect combination of each of the benefits found in both traditional quad rails and M-Lok handguards. Integrated rail sections on the front of the handguard allow you to install various picatinny accessories ranging from bipods to lights without the need to purchase extra adapters. The M-Lok body of the rail serves to significantly reduce weight while allowing you to attach accessories at a much lower profile than standard picatinny allows.
    2. Effortless install. Absolutely no barrel nut timing required. In addition to being incredibly easy to install, the system developed also solves the biggest problem faced by handguards today – unwanted slipping. By engineering an anti-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.
    3. Ready for every condition. Any time. Anywhere. Exceptionally rugged and built to last a lifetime. Every rail is meticulously designed to excel under any mission it undergoes.

First AR build

I’m building my first AR, and want everything on this one to be good quality. I’m enjoying seeing it come together, but now that I got this handguard on, it looks amazing. I did a lot of research and was going to spend 300 dollars on a handguard, before stumbling on to STNGR, that being said, it was a perfect fit, everything is so clean, A++.

I installed this hand guard with ease and it has improved my accuracy by 25% on the range. I used the A2 site and cut it into a low boy gas block. In this conversion that was actually the biggest challenge.

1018 steel barrel nut

Fits perfectly, got it on just waiting for a couple more parts to come in to finish my AR

Great handguard

Love it

VYPR Handguard

This upgrade was too easy! I added on the steel barrel nut for just a few more dollars, but otherwise this was a straight from the box to the range project. I will be looking at STNGR products as I begin an sbr build next!

Love it!

Best floating handguard ever made!

Fantastic Rail with easy installation

Definitely can tell it's a quality handguard and American made. Well worth the price
