Ships Straight to You, Legal Under Federal Law
Because the only component of the AR-15 that's considered a firearm is the stripped lower receiver, rifle upper assemblies are not considered firearms. The ATF doesn't regulate their sale or ownership, so you can purchase your upper and have it delivered directly to your door. Completing your AR build with an 80% lower allows you to avoid the gun store fees, high prices, and extra taxes entirely.
Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
