Get back to basics. Learn what it means to be solely responsible for your 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 upper assembly that when paired with a built LR-308 lower receiver, will yield you a solid and capable LR-308 rifle. You'll need a stripped lower receiver not included, then assemble it with the provided prebuilt upper assembly, then add your 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 optics of your choice and you are ready for the range.
