The Radical Firearms 20" 6.5 Grendel Complete Upper Receiver is a law enforcement grade, drop-in solution for your next AR build. Crafted with quality materials and covered by Radical’s lifetime warranty, this MIL-SPEC upper receiver provides an outstanding solution for any budget. Arrives at your door with the hard work done. Complete this build with your favorite lower receiver and sights then head for the range!

Includes the Radical Firearms M-LOK Hybrid Rail System which offers a generous 1.8” inside diameter that easily accommodates most suppressors. Lightening cuts along the rail reduce weight and aid in rapid cooling while M-LOK mounting points and MIL-SPEC Picatinny continuous top and short bottom rails provide space for your favorite sights, optics, and accessories. Features anti-rotation tabs, non-rotating QD sling mounts, and a tough hardcoat anodized finish.

Safety Note: Choosing 6.5 Grendel comes with an added complication. There are “Type I” and “Type II” bolt/barrel specifications out there, and you CAN NOT mix and match parts for each of them without risk of damage and/or injury. Type II is by far the most popular configuration, but pay attention to what you are buying! A Type I bolt won’t chamber rounds in a Type II barrel at all. Even worse, a Type II bolt mated to a Type I barrel will create excessive headspace and result in a rifle that is dangerous to fire.
