Get back to basics. Learn what it means to be solely responsible for your own rifle by building 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. You'll need a stripped lower receiver (sold separately), then assemble it with the provided prebuilt upper assembly, lower parts kit, and butt stock/buffer tube assembly. All you'll need to do after assembly is pick out a set of backup sights or optic of your choice, and get some mags and ammo.
Choose between including a lower in your kit or buying the kit without one.
