Airtac Glock to MP5 Magazine Adapter + MP5 Mags

I’m looking to sell a brand new & unused Glock to MP5 HPA adapter.
I’ve had it sitting spare for so long it won’t be accepted back by Airtac, so here it is, it just needs a donor magazine to go together with.

I’m looking for £50 for it, plus £5 for postage.

Please feel free to message me with any questions.
