Shell Ejecting Gas Blowback AirSoft Pistol - Marushin G21 DUAL MAXI (8mm)

I'm possibly selling the rarest gun in my collection, my Marushin Glock.
Preferably for Showcase/Plinking use, as 8mm bb's are not commonly found.
Comes with 6 shells and a holster.
Ships only within the EU.
This is a rare chance to get your hands on a shell ejecting airsoft pistol.
