Considerations & Trade-offs

  • Chambered in 300 Blackout, so ammunition choice and intended use should be matched carefully to the rifle’s setup and your application.
  • The patented polymer hybrid Omni upper and lower receivers may be a consideration for buyers who prefer traditional all-metal receiver construction.
  • The 15" free float aluminum M-LOK rail offers a longer handguard profile, which can be more than some hunters want on a compact field rifle.
  • The included Ammend2 magazine is listed at 30-round capacity (.223/5.56), so verify magazine compatibility with your intended 300 Blackout use and local regulations.
