Gain a new skill and get empowered. Learn what it means to be solely responsible for your own rifle by building it yourself. Take up the .308 caliber by building an LR-308, and stretch your shooting out to longer ranges more accurately than your typical AR style rifle.
We present to you a no nonsense build kit that when paired with an LR-308 lower receiver (sold separately), will produce a solid and robust .308 AR. All that's left is to pick out either a set of backup sights or optic of your choice, and get some mags and ammo. See below for additional specs and details.
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock.
