Double Bell 5" Threaded Aluminum Outer Barrel for Hi-Capa 5.1, Luxury Gold

Swapping the outer barrel on a Hi-Capa is one of the easiest upgrades you can do. This Double Bell barrel is a 5-inch replacement for Tokyo Marui-spec Hi-Capa 5.1 gas blowback pistols. It threads at the muzzle, so you can run a compensator or mock suppressor if you want to balance the slide's forward weight.

The barrel is machined from aluminum. The finish is a bright gold plating called Luxury Gold. It stands out against a black or slide-finished frame.

Installation is drop-in. You pull the slide off the frame, remove the inner barrel and hop-up unit, then seat the new outer barrel into the slide. The inner barrel and bucking go back in the same way. You do not need to tune the hop-up or adjust the nozzle for this swap, assuming your inner barrel and bucking are in good shape.

This is an outer barrel only. It does not include an inner barrel, hop-up chamber, or bucking. If your goal is better accuracy, you will still need to upgrade those parts separately. If you just want to change the profile or add a threaded muzzle, this does the job.

Check the product listing or contact the seller to confirm the thread pitch before you buy.
