Availability: In stock

The Quarter Circle 10 Side Charging Upper Receiver is a highly rigid upper receiver designed specifically for pistol-caliber AR builds. Our upper receiver design is derived from the industry-first Gibbz Arms G9 receiver, and with the help of Gibbz engineers and our pistol caliber expertise, we've brought you the best possible choice for a dedicated pistol-caliber build. The QC10 Side Charging Upper features:

  • Latching, non-reciprocating, left side charging handle

  • 6061 Billet Construction (Note: There may be a slight discrepency in black coating, when paired with 7075 Billet Lower Receivers.)
  • Spring-loaded rear door minimizes blowback when firing suppressed

  • Widened ejection port for clean ejection of large-bore cartridges

  • Slick side aesthetic perfectly complements QC10 Lowers

  • Compatible with GSF, GLF, and CLT9MM Lowers

  • This model not compatible with QC10 Keymod Handguards

  • QC10 Side-charging uppers designed and manufactured with Gibbz Arms technology

  • Handguards with overlapping anti-rotation tabs may not be compatible with QC10 billet upper receivers, including Side Charging uppers.
