The Ruger AR-15 Upper Receiver, Stripped (Ruger part #91004) is a genuine Ruger factory upper receiver. It’s a bare AR-15 upper receiver for builders who want to pick their own forward assist, dust cover, barrel and handguard. Ruger builds these to its own standard for AR-15 pattern rifles, but with so many AR parts on the market Ruger can’t guarantee fit with every other maker’s components.
