Finish off your AR-15 build or give your current one a significant improvement with the Rainier Arms EVOLUTION Free Float KeyMod Rail System.
It is machined from the famously tough 6061-T6 aluminum to give you a handguard that can stand up to the most rugged conditions without weighing your weapon down. Rainier Arms applies type-3 hardcoat anodize for a lifetime of protection against corrosive elements.
The EVOLUTION goes above and beyond with its accessory mounting capabilities. For starters, there is a continuous Picatinny rail on top that gives you ample space for your optic of choice. There are also KeyMod slots on the three remaining sides for grips, lasers, lights, or anything else you wish to attach. Finally, it has quick detach sling mounting sockets on both the left and right sides at both ends. Plus, you won't find it coming loose or rotating because the anti-rotation tabs keep it right where you mounted it!
This Rainier Arms EVO KeyMod rail system lightens the load of your AR15, gives you lots of accessory mounting options, and prevails even in the most aggressive environments.
