Golden Eagle 15" KeyMod Full Metal Upper Receiver for Golden Eagle Full Metal Lower Receivers, Black

Upgrading from a polymer upper to full metal changes how a gas gun feels in the hand. The Golden Eagle 15\" KeyMod upper brings alloy construction to a platform that often ships with plastic externals, adding weight and realism without compromising the internals. If you're building a Golden Eagle gas blowback rifle and want the look and heft of a metal receiver without custom machining, this is the direct swap.

What you're getting. This is the upper receiver only—it does not include a lower, internals, or magazine. It pairs with Golden Eagle full metal lower receivers. The note on compatibility matters: it will not mate correctly with Golden Eagle's polymer lowers, so if you're replacing a broken upper on an older plastic-lower build, verify your lower's material first.

KeyMod over Picatinny. The handguard uses KeyMod slots at 3, 6, and 9 o'clock rather than a full-length Picatinny rail. That keeps weight down and lets you mount grips, lights, and lasers with KeyMod-compatible accessories. If you're committed to old-school Picatinny rails, you'll need adapters or a different handguard.

Weight and handling. At 2.57 lbs, this upper adds real mass compared to polymer alternatives. That improves balance on a gas blowback build and gives a more substantial feel during active use. It's not a lightweight upgrade—expect the gun to carry like a full-metal platform once assembled.

Adjustable hop-up included. A one-piece metal hop-up chamber comes integrated, which is stiffer and more consistent than flex-prone polymer designs. You can dial in backspin without swapping parts, and the metal construction resists deformation from nozzle pressure over time.

Before you buy. This is a parts upgrade, not a complete rifle. You'll need a compatible Golden Eagle full metal lower, a gas magazine, and your choice of optics or iron sights. Battery and charger are not relevant for gas guns, but you will need green gas or propane with silicone oil to operate it.
