The New Frontier Armory C-9 Slick Side Upper Receiver is unique in the pistol caliber AR-15 market. Machined from solid billet 7075-T6 aluminum with a durable MIL-SPEC hardcoat anodized finish, this upper is fully compatible with all standard AR-15 or AR-9 components, as well as most aftermarket parts. What really sets it apart, however, is the integrated Last Round Bolt Hold Open (LRBHO) technology that allows for reliable bolt lock back when combined with a Glock magazine compatible lower. Purpose built for pistol calibers, and designed to match the lines of the New Frontier C-9 and C-45 Billet Lowers, the C-9 Slick Side Upper is the perfect option for your next pistol caliber AR build!

  • Integrated adjustable Last Round Bolt Hold Open for Glock compatible lowers
  • Compatible with all standard AR-15/AR-9 components
  • Lightweight slick side design without forward assist or ejection port cover
  • Purpose built without gas tube slot for blowback action

Please Note: While tuned from the factory, minor adjustments may need to be made to the small hook end of the wire inside the upper for consistent function of the LRBHO.
