I purchased a Crosman Shockwave in .177 and am not happy with the performance. I did not do enough research! i am interested in swapping the .177 barrel for a .22 barrel. any input of the feasibility of this?
You should start a new thread versus hi-jacking an old one. That said, most of the noise from a break barrel gun is mechanical due to the release of the piston. A new barrel or moderator is not going to fix that.
