Marushin MP40 for sale

Hi all

I recently bought a Marushin mp40, I've fired 2 rounds through it, but to be honest, I'm not a fan of ww2 weapons (don't know why I bought it, lol)

It comes with the original leather sling and obviously a metal magazine, it has metal parts, but think it must be abs etc.

I'm looking for a metal M16 converted to fire the new tanaka rounds, if anyone fancies a PX, please let me know.

I paid £170 for it, so looking for my money back.

Thanks
