I'm after a super quiet budget pcp/silencer combination if one exists. Its for rat control at my allotment and backs onto houses. The cheaper and quieter the better. I've looked at the Kral NP03, Gamo GX40 and Artemis P15 but I don't think they are particularly quiet on their own? I've found a company Air-Fective Tuning that seem to do good silencers but they don't answer the phone or reply to messages. There is a Vermin Hunters YouTube video around the P15 but I cant track down the barrel shroud they recommend. Please help.
