Zius BK1S/BK2S Receiver Shell

The Zius BK1S/BK2S Receiver Shell is the outer housing for the BK1S and BK2S, so it takes the brunt of everyday handling, drops, and general wear. If your stock shell has cracked, chipped, or just looks tired after heavy use, this is the direct replacement part to bring the blaster back to spec.

It's available in two finishes, yellow and grey, so you can either match your existing BK1S or BK2S exactly or use the swap as a chance to change up the look of your build. Since it's a purpose-built replacement shell for this specific platform, no extra fitting or modification is needed beyond transferring your internals across from the old shell.
