Golden Eagle Airsoft Rear Sight w/ Fiber Optics for Hi-Capa, Green/Red

The Golden Eagle rear sight with fiber optic replaces the factory rear sight on Tokyo Marui-spec Hi-Capa pistols. It swaps out the plain notch for a fiber-optic rod that catches ambient light, giving you a brighter reference point when aligning your shot. In bright conditions, that extra contrast can shave off a split second on target acquisition.

The housing is machined aluminum, not polymer. That means it holds zero better under recoil and won't wear down the way cheap sights do. The fiber optic rod comes in green and red variants—pick the one that suits your lighting preference or match it to your front sight.

Compatibility. This fits Tokyo Marui-spec Hi-Capa pistols. If your gun came from Marui, KSC, KWA, or any brand copying that spec, it should slide right in. It does not fit 1911 GBB pistols running non-TM specs or full-metal guns with different dovetail dimensions.

What you get. The package includes just the rear fiber sight. If you're replacing a complete sight system, you'll need a matching front sight separately. Installation is drift-install—no tools beyond a punch and a bit of patience. If you're not comfortable drifting sights, budget a shop visit.

Who this is for. Competition shooters who need consistent sight pictures across lighting conditions. If you're running a plinker or a dedicated CQB pistol, a standard rear sight is probably fine. This is for when you care about that last fraction of a second.
