Cavia Airsoft Tech Mounting Kit For Polarstar F2/Silverback MDR

I’m selling this Cavia Airsoft Tech mounting kit that allows you to install a Polarstar F2 engine into a Silverback MDR.

I’ve sold the MDR & F2 separately, with neither buyer wanting the kit, so here it is.
It’s already partially assembled, and comes with everything needed to complete he install, including a replacement trigger board that allows it to still use semi and full-auto.

I’m looking for £95 for the kit, plus £5 for the postage.

Please feel free to message me with any questions.
