Golden Eagle 15" Battle Polymer Upper Receiver, Black

If you're building a gas blowback rifle from the ground up or swapping out a worn upper, the Golden Eagle 15" Battle Polymer Upper gives you a solid foundation without the weight penalty of all-metal builds. At 2.43 lbs, it's noticeably lighter than a full aluminum counterpart, which matters when you're holding it up for hours or running long days on the field.

Rail system. The handguard provides mounting real estate for accessories while keeping the overall profile manageable for CQB and vehicle work. The rail type is Weaver/Picatinny, compatible with standard airsoft optics and accessories. The 15-inch length gives you room to mount a red dot, magnified optic, or backup iron sights without needing a separate riser.

Full-length top rail. The flat-top receiver carries a continuous Picatinny rail from the front of the upper back to the rear sight block. The rail is metal, which helps it hold zero under recoil.

Hop-up compatibility. The hop-up is adjustable and designed to work with Golden Eagle polymer lower receiver systems. If you're already running a Golden Eagle gas lower, this is a plug-and-play match. The hop-up adjustment is accessible and holds its setting, which matters for consistent grouping.

What you need to know. This is an upper receiver only — it ships without a lower receiver. You'll need a compatible Golden Eagle polymer lower to complete the build. The metal barrel and rail system are included. No battery or charger is required since this is a gas gun component, but you will need green gas or propane with silicone oil for operation.

This upper is for builders who want a lightweight, accessory-ready platform without paying for a complete rifle. It's not a drop-in replacement for metal M4 uppers if you're chasing all-metal realism — it's a functional, lighter alternative for players who prioritize weight savings and modularity.
