Bought this a little while ago from HK. Decided Im probably not gonna use it hence reason of sale. It's essentially brand new only been shot a handful of times. Comes with 2 x 6 cartridges (12 in total). The 6 cartridges that are loose are the front loading kind which means the fps from first shot of a new co2 bulb will be just about site legal. Second cartridge type which are still sealed in the pack are the rear loading kind. These make reloading nice as you don't need to change the cartridge at all, only pop a new bb in. I know this from owning another umarex SAA that had these cartridges. 
Will be sent in original box with instruction manual.
Asking £130 postage included
