6.5 Grendel Rifle Kits
Mil-spec hardware made to maximize 6.5 Grendel's accuracy.
The AR-15 is a great rifle but for some, 5.56 and .223 just doesn't pack a big punch or long enough reach. For others, 6.5 Creedmoor and .308 Winchester are too big to lug around. So, the AR's .308 platform is out of the question. That's where the 6.5 Grendel AR-15 comes in. This .264 cartridge bridges the gap between the .22 and .30 calibers popular with the black rifle. Grendel offers .308 performance in the .22-cal platform, providing the best of both worlds: You get longer reach and power than 5.56, and lower recoil and cost than Creedmoor or .308.
Each Kit Includes
- (1) 6.5 Grendel Barreled Upper
- (1) Mil-Spec Lower Parts Kit
- (1) Buffer, Tube, Spring & Buttstock
- (1) Bolt Carrier Group w/ Charging Handle
To complete your Grendel build, purchase separately an AR-15 billet, forged, or polymer 80% lower. Completing your lower is easy and requires an 80% AR-15 jig, which comes with the necessary bits and instructions.
