Description
Get back to basics. Learn what it means to be solely responsible for your own rifle by build it yourself. Go for the .308 caliber by building an LR-308, and stretch your shooting out to longer ranges accurately than your typical AR style rifle.
We're bringing you a no nonsense build kit that when paired with and build off an LR-308 lower receiver, will yield you a solid and robust LR-308 rifle. Simply finish milling out your 80% lower receiver, which you can get here, and then assemble it with the provided prebuilt upper assembly, lower parts kit, and butt stock/buffer tube assembly. Then all you need to do is pick out either a set of backup sights or optic(s) of your choice, and get some mags and ammo. See below for additional specs and details.
