Golden Eagle 14" Carbine Length Complete Polymer Upper Receiver, Black

If you're building a Golden Eagle gas blowback rifle or replacing a damaged upper, this is the drop-in part that skips the assembly work. The Golden Eagle 14" carbine complete upper comes ready to mount with its barrel, handguard, and hop-up already installed. You mate it to a compatible Golden Eagle polymer lower and you're looking at a functioning gas rifle platform without hunting for individual components.

What's in the box. The upper receiver, barrel assembly, and handguard are all included as a single unit. A 350 mm inner barrel is already seated, which is roughly 13.8 inches—close enough to the advertised 14" carbine length for typical M4-style builds. The adjustable hop-up chamber is installed and ready, so you do not need to source or fit a separate bucking and chamber assembly.

Materials and weight. The receiver itself is polymer, keeping the overall weight at 3.1 lbs for the complete upper. The barrel and rail system are metal, which matters for durability and heat resistance during extended use. The rail system provides mounting space for foregrips, lights, lasers, or rail covers, while the top of the receiver carries a full-length Picatinny rail for optics.

Compatibility is narrow. This upper is designed specifically for Golden Eagle polymer lower receivers. It will not mate with Golden Eagle metal lowers or any other brand's lower. If you are building from scratch, verify your lower receiver type before ordering. If you are replacing a damaged upper, confirm your existing lower is the polymer variant.

What you still need. This is an upper receiver only. You will need a compatible Golden Eagle polymer lower, a gas source (green gas or propane with silicone oil), and magazines for the platform. The package does not include a magazine, gas tank, or charging handle.
