PSA Sabre Key – SHOT Show 2026 Reveal

PSA kicked off SHOT Show 2026 by unveiling the Sabre Key, a new and unique underbarrel-mounted shotgun system designed for AR-15 platforms.

 What Is the Sabre Key?

• Underbarrel-mounted short-barreled shotgun
• Designed to mount to an AR-15 similar to an M203-style launcher
• Uses a proprietary PSA mounting system
• Cannot be converted from a standard 570 shotgun at home
• Based on the 570 platform, but uses a different receiver

Caliber, Barrel & Capacity

• 12 gauge
• 10-inch barrel (standard configuration)
• Built-in front hand stop in the hanger
• Compatible with:
  • 2¾-inch shells
  • 3-inch shells
  • 3+1 capacity

AR-15 Compatibility

• Designed to work with M4A1-profile AR-15 barrels
• Mounts using PSA’s custom-developed mounting system
• Intended as a dedicated underbarrel system, not a conversion kit

NFA & Shipping Notes

• Due to recent NFA tax changes, there is no additional tax fee
• Through PSA’s partnership with Capital Armory, the Sabre Key can be shipped directly to your door

Project Status & What’s Next

• PSA plans to launch the 570 pump first
• After that, the team will transition to:
  • The Sabre Key
  • The semi-auto 570
  • More updates and videos will be released leading up to SHOT Show
