Snowpeak PP20 Regulator

The rubber O ring went on mine today. The one on the regulator valve. I know little about air pistols so was pissed at this failure because it’s a new gun. The rear sight part that widens or reduces the Cut-Out wobbles. I’ve padded it with card. Snowpeak don’t reply to email and the distributor sent a return form but I have to pay £40 postage. Nice wee gun but buy at your own risk.
