This one's a cutie in our opinion. Evike.com's The Gun Corner features today the Maruzen Scorpion VZ61 Gas Blowback Machine Pistol and since it can fire at semi and full auto can be an even more capable backup gun in CQB games than a GBB pistol. This has fixed front and rear sights, steel folding stock, and an ergonomic pistol grip. As for gas, 134a is recommended for this baby which will cost you US$199.00 to add to your arsenal.
