A little back story, I know I haven't been on the forum much, I pretty much changed hobbies from paintball to dirtbikes and four wheelers. I didn't quit though, I still play now and then even though most of the people I used to play with have left for school and such. Any who I am now a Journeyman Machinist, I will be graduating in March but at school I have made things like reed spacers for my bikes, and a rest for my bow, I also have many more projects I could make but with work and school, it is difficult to find time to stay after class and make them. I finally found time and commited to one of my long awaited projects, a replacement piston for my cp reg.
Doesn't look like much I know, but here is the stock piece.
This piston cycles faster and more consistently, I will have chrono numbers to prove it this weekend. I do not own a cp shorty reg or one of the newer ones so I do not know if this will work with other cp regs. What do you guys think?
