Every AR-15 rifle upper available for sale has been precisely assembled by our team to guarantee MOA accuracy and utter reliability. We work with top gunsmiths and arms makers to configure each upper rifle assembly with the right mil-spec components, the best coatings and barrel treatments, and rugged, accurizing free-float handguards. All rifle assemblies are put together by experienced shooters who properly torque and season barrel nuts, and ensure proper alignment with every handguard.
Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of certain firearm 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.
