I am glad you posted this about the NP Bushing Kit. Just three weeks ago I got an email from Rick Eutsler at Airgunweb concerning the fit of the bushin in the piston in his new Crosman Titan.I immediatly called Crosman parts department and ordered a new piston. The part number had changed. I received the new piston today and sure enough Crosman has changed the I/D size of piston. My solution would be to have all new NP bushings made but that will take up to a month. I will make an announcment when I receive the new bushings.Sorry for the issue.Gene
