Radical Firearms' 7.62x39 complete upper is the perfect excuse for AK owners to build an AR-15 utilizing the same caliber. Put that Russian ammo you've stockpiled to use in an American weapons platform to increase the variety of your arsenal and enjoyment at the range. This upper comes completely assembled with a 16" barrel, forged M4 upper, nitride bolt carrier group, Mil-STD charging handle, and 15" handguard. Radical's heavy contour 7.62x39 barrel is 4150 chrome moly vanadium and features a 5/8x24 threaded muzzle with A2 flash hider. The standard carbine length gas system uses a low-profile gas block which is tucked neatly under the RPR M-LOK rail. Not only does it achieve the perfect tactical aesthetics, but it also has plenty of room to mount all of your favorite accessories. Instead of sourcing each individual part and spending time assembling one yourself, this complete upper only needs a lower and your sight of choice before hitting the range. Whether you have a stockpile of 7.62x39 or just want to add some variety to your AR collection, Radical's 16" upper is an excellent choice for your next build.
