ODIN Works is an innovative group creating and manufacturing high quality AR-15 products and accessories. They bring their experience and knowledge to the consumer through progressive design and technology.

The 20" 6.5 Grendel Intermediate Length Complete Upper features an ODIN Upper receiver, dust cover, and eXtended Charging Handle. The case hardened 8620 steel bolt carrier group has been finished with a black nitride coating for superior corrosion resistance while the heat-treated MIL-SPEC bolt is CNC ground for a precision fit.

Built with a 1 MOA guaranteed ODIN 20” Barrel chambered in 6.5 Grendel with an adjustable gas block that features 20 clicks of adjustment. The lightweight 15.5” M-LOK freefloat handguard provides a continuous picatinny rail, QD holes, and M-LOK slots to mount your favorite accessories.

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.
