3D model description

Ever wanted a rare-looking piece either for target practice or some fields but can't find any World War One-type weapons? If you have a KJW MK1 airsoft pistol, this is a conversion kit for you! Better yet, this requires ZERO alterations to your airsoft pistol as all parts are slide or drop-in!

The Borchardt C-93 was developed by Hugo Borchardt in 1893. You may know his assistant and then successor Georg Luger for his later design of the Luger Parabellum. The C-93 first introduced the unique toggle 2-piece arm that opened the breech for every subsequent cartridge fired.

Read more about the historic pistol here: https://en.wikipedia.org/wiki/Borchardt_C-93

Instructions:

A) Disassemble the original pistol:
1) Unlock the upper receiver from the frame using the lever spring system on the back of the handle and pull it loose. Pull out the fake charging handle.
2) Use the Allen key to unscrew the outer barrel from the upper receiver. Slide off the original upper receiver housing and barrel.

B) Assemble the conversion kit once printed:
1) Slide the system into the inner receiver part and slide the fake charging handle.
2) Slide the outer barrel onto the metal inner barrel and afix using the Allen wrench. Glue in the front blade sight.
3) Reassemble the receiver and frame using the lever spring system. (NOTE: if pulling the trigger does not make a hammer strike, widen the lower hole on the inner receiver part only)
4) Pop on the upper shell simulating the Borchardt pistol mechanism. Glue to printed inner receiver if desired.

Note, you get a more detailed exterior receiver than I have in my picture as mine was a prototype.

Accuracy is not guaranteed but then again, you were looking at this if you wanted style!
