how powerful is HK' CO2? i've heard some1 said about 3 pounds per feet - not sure.
i'm in UK. my CO2 is .177 - 6 pounds per feet, can do 2 side of seagull which from top of house. about 3rd floor of HK flat...
don't say i'm cold blood. CO2 gun in UK is for bird and rat shooting
only way to mod is longer barrel, heat up the CO2 bottle, and some CO2 rifle can use bigger CO2 bottle. can reach 10 pounds per feet.
