Shoei Mkb42 (H) Modelgun

Hi everyone, I’ve just recently bought an Shoei Mkb42 (H) modelgun the dummy cartridge version and was a bit disappointed that I could only manually cock the chamber and the shells can eject but can’t never fully fire it. Is there any way to modify it to firing full auto as I’ve seen in a few of cerwyn videos

Hi,

I bought mine as a cap firing version from Shoei when they released about 150 of them. As standard, firing was OK but needed improving.

Converting a cap-firing model to a great firing model took well over 12 months of hard work and designing. Shoei supplied a Firing Chamber which needed modifying to accept a different detonator pin. The original cartridges were replaced with home made aluminium and brass versions, single cap, not two caps as Shoei's design. The bolt was remade, secured to the bolt carrier to reduce risk of breakage and then fine tuned to get it right.
An awful lot of work on an already firing model, but well worth it.

Converting a non-firing version would take considerably more thought and work. If you did start planning it, be sure you can source caps otherwise it'll be pointless!
