AR15 Pistol Upper

AR15 Pistol Upper

Each AR-15 pistol upper is proudly assembled by our own team, using appropriate torque specs, mil-spec components, and free-float handguards. Available in 5.56 NATO, .223 Wylde, and 300 Blackout chambers, there's a barreled pistol upper listed for every popular build. We stuck with faster 1:7 and 1:8 twist rates and used pistol gas systems (of course) to ensure each upper is capable of providing accuracy, stability, and reliability in a compact profile.

Not a Firearm Under Federal Law

AR-15 upper receivers, including pistol uppers, are not considered firearms under federal law. They do not require a background check nor FFL transfer to buy, ship, own, or use with your completed lower receiver assembly. However, 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.
