    2240-Type My 2240 to .177 Project

    I installed a 2300s valve spacer and hammer spring along with a 10 inch.177 barrel. I thought I was getting about 110 shots. I just confirmed, in a 60f garage at 7yrds, that I got 135 shots before the 136th finally dropped half an inch and crept further down for the next 4 and I stopped. Crazy

    I'm thinking about buying a ch2021. I've been studying the parts catalog but I'm looking for a copy of the owners manual too. Can anyone provide it or direct me to a link. Thank you

    Introductions Hello from California

    Hello, Until 3 years ago I'd never owned any type of gun. When trying to deal with a yard pest I started looking into pellet guns. First I found out it's illegal to shoot in the city limits. But I was intrigued by all the different types of airguns. I also discovered people shoot in...
