Mechlabs XX-Mod HPA Engine

I’m looking to sell a Mechlabs XX-Mod HPA engine that was previously part of an ARP9 build that i’ve replaced with a couple of GBBR projects.

It can be a bit finnicky to get everything adjusted to the point it starts working, but it is quite impressive having a fully mechanical HPA engine that is also select-fire.

I’m looking for £225 for the engine, plus £10 for postage.

Please feel free to message me with any questions.
