Golden Eagle 13" Battle Full Metal Upper Receiver, Black

Building or rebuilding a Golden Eagle gas blowback rifle starts with the foundation. The Golden Eagle 13\" Battle Full Metal Upper Receiver is that foundation: a one-piece metal upper designed to mate with Golden Eagle's full metal lower receivers for a complete gas gun build.

What the metal construction means. Full metal alloy receiver set, outer barrel, and handguard assembly. This is not a metal outer barrel on a polymer body. The entire upper is machined and cast metal, which gives you the weight and feel of a real firearm and the durability to handle repeated gas blowback cycling without cracking or warping. The trade-off is weight at 2.57 lbs, so this is a substantial build rather than a lightweight CQB setup.

The rail system. The forend follows the Troy Alpha Rail pattern, which means you can mount standard accessories—foregrips, lights, lasers—without proprietary adapters. The top rail is a full-length monolithic Picatinny/Weaver rail, ideal for optics from red dots to magnified scopes. No flimsy detachable rails; the top rail is integral to the receiver.

Compatibility is specific. This upper is engineered to mate with Golden Eagle full metal lower receivers only. It will not fit polymer Golden Eagle lowers. If you're upgrading from a polymer lower to metal, you need both the upper and the matching metal lower. The hop-up system is built into the upper and is directly compatible with Golden Eagle metal lower hop-up chambers, so you don't need to swap internals.

What you get. Just the upper receiver assembly. No lower, no magazine, no gas source. You'll need a compatible Golden Eagle metal lower, a gas magazine that fits the platform, and a green gas or CO2 source to operate it. The adjustable hop-up is included and pre-installed.

This is for players building a custom gas blowback rifle or replacing a worn upper on an existing Golden Eagle platform. If you're looking for a complete rifle out of the box, this is not it. If you want a durable, full-metal upper for a build that will see regular use, this is the right starting point.
