6.5 Grendel Rifle Kit (20” Parkerized Barrel & 15” M-Lok Handguard, Side-Charged) w/ 80% Lower (1:8 Twist)

If you're looking for an intermediate-weight AR platform rifle that's roughly the size of an AR-15 but will out-perform the LR-308 in terms of distance, stop right here. Check out the first of our new line AR rifles chambered in 6.5 Grendel! Build yours today, and set yourself apart from the rest of the "gun guys" out there, while you're dinging steel from 1,000 yards away.

This build kit comes with a 20-inch parkerized barrel chambered in the 6.5 Grendel caliber with a 1:8 twist rate. You also get a 15" handguard that comes with lots of M-LOK real estate for mounting your bipod, vertical grip, tac light, or whatever else you could think of. The cool thing about this kit is that unlike traditional AR type rifles, this one is side-charging, meaning you chamber your mag's initial round by pulling the handle that sticks out the right side of the upper receiver. Pretty badass, huh? We thought so too. After that, all you need are mags and ammo, and either backup sights or the optic of your choice. Get building and then get to kicking some steel or paper ass from the next county over!
