Why This Kit Works
The .300 Blackout cartridge excels in compact platforms, delivering rifle-level power in a pistol-length package. The 7.5" barrel optimizes velocity while maintaining the round's subsonic capability. Free-floating handguard design promotes accuracy, while the billet upper receiver ensures tight tolerances and durability.
This is a stripped upper build—you'll need to source a lower receiver separately to complete your rifle.
