Kross Airsoft Design MK23 EM2 Carbine Kit

The EM2 was a British post-war bullpup rifle that never made it to widespread service — but it had one of the most distinctive silhouettes ever fielded. KAD's MK23 EM2 Carbine kit channels that profile into an airsoft conversion, turning your TM MK23 pistol into a full-bodied bullpup carbine that genuinely turns heads on the field.

Built-in dovetail rail (with picatinny option available) lets you mount period-appropriate optics or modern dot sights as you prefer. The removable dummy magazine forward of the trigger group serves as a clever Allen key holder — KAD's nod to the fact that everyone loses theirs eventually.

Note that this is a custom-build product. The kit is bold, rugged, and fully functional, but it's not a cheap mass-produced part. It's for shooters who want their gun to be a conversation starter as much as a tool.

Bullpup mechanics on a pistol

Bullpup designs put the action behind the trigger group, which means a long barrel can sit inside a short overall package. On an MK23 conversion, that means you keep the MK23's renowned 6.01mm tight-bore accuracy with the muzzle pushed forward, and a stock anchoring the rear of the gun. It's compact, accurate, and entirely unique — there's nothing else like it on the airsoft market.
