Seburo CX

A resin replica of the Seburo C-X, built on the frame of a Walther PPK/S airgun.

The Seburo Compact-eXploder (more commonly referred to as the Seburo C-X), is a simple blowback-operated, magazine fed, bullpup compact machine pistol . Very similar to the Bobson in overall proportions, the C-X is different visually and mechanically due to the extended slide on the top of the weapon, bullpup configuration and the unconventional magazine with an unusually small magwell that has no visual magazine retention mechanism or magazine release. This unconventional and exotic (though likely problematic) design has possibly lead to the following of the weapon.

Because of the length of the barrel in comparison to the slide, the C-X can outperform other compact weapons, but thanks to the height of iron sights above the barrel, a problem shared with, originally and most notably, the M16, without proper training the weapon is seemingly inaccurate at medium to short ranges, with you having to aim above the target to score a successful hit. One misconception is that the C-X also exhibits satisfactory precision over long ranges, similar to a rifle. This is false as, while the barrel length and difference in cartridge would make it superior to many pistols, the lack of a stock, the short barrel when used in conjunction with a larger, more powerful caliber of ammunition taken into account, the sub par iron sights and the minimal weight of the gun whilst firing powerful ammunition leading to overwhelming recoil would make this pistol very unlikely to connect shots with distant targets and so can only be relegated to a weapon intended for close-quarters combat. 

Alongside being limited by range and heavy recoil, the C-X is impractical, as it would require extensive training and, thanks to its exotic bullpup design, it would require proprietary holsters, proprietary magazines (which utilise proprietary ammunition) and extensive modifications for it to ever begin to comply with standardised accessories e.g. flashlights, optics, laser aiming modules, ect. These are all flaws inherent to this unconventional design that would make it an impractical and expensive weapon that offers no clear advantage over competing products and Seburo would not likely land a successful contract for the wholesale purchase of this firearm in large numbers, due to the extensive cost to the buyer and impractical nature of the weapon in a large-scale combat scenario.

Compact-eXploders are seen sometimes in the original manga series, as well as in the 2004 CGI movie.
