Derya DY9 9mm Complete Upper Receiver Assembly – Island Barrel, Black

The Derya DY9 9mm Complete Upper Receiver Assembly provides a factory replacement or spare upper for the DY9 pistol-caliber carbine platform. This assembly includes the upper receiver, island-style barrel, charging handle, and bolt carrier group, allowing shooters to maintain their DY9 or build a backup configuration without purchasing an entirely new firearm.

Constructed with a black finish matching factory DY9 specifications, this complete upper is designed as a drop-in assembly for existing DY9 lowers. The island barrel configuration places the front sight on a raised platform ahead of the handguard. Installation requires basic familiarity with AR-pattern takedown pins and upper/lower mating—no gunsmithing tools necessary, though proper headspace verification is always recommended when swapping complete uppers.
