Our Ar-15 rifle build kits contain everything you need to build your own assault rifle at home. These are Non-FFL and require no background check and ship straight to your door. They are 100% legal to own because the kits do not include complete lower receivers but we sell 80% lower receivers which are also non-FFL. We offer a variety of calibers including larger AR-10 variants like .308 and 6.5 Creedmor and AR-15 variants like .223, 5.56 NATO and .300 BLK. Everything you need to assemble your AR-15 is waiting for you.
