    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 I love the look of it . Second installed easy, yet best mount up design I have used. Third like the wrench to install barrel nut, which was included. fourth I purchased steel barrel nut option, because if I ever want to take the handguard off later less worry as much about stretching the threads. STNGR has me for my future builds. I would like one of each handguard styles. AAA quality and affordable price. Thanks STNGR.
