If you're looking for an intermediate-weight side-charging 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 of 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.
The Guide to The 6.5 Grendel AR
This side-charging 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.
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock. It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 jig to fabricate a receiver, sold separately.
Here's the beginner's guide to 80% lowers.
