Get your hands on one of the sleekest, lightweight rifle kits in our catalog. This mil-spec AR kit comes to you chambered in 5.56mm NATO, the same caliber as our military's rifles. It comes with an ultra-light, skeletonized handguard that looks great and feels even better. It's all paired with mil-spec lower parts and an M16 BCG.
This kit comes with all parts required for assembly, except for the firearm component, a stripped lower receiver. This kit's mil-spec configuration guarantees it will work with just about any 5.56/.223 receivers on the market.
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. This kit does not include a stripped lower receiver (the firearm component). 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.
