You guys are way more into the airgun stuff...Used to shoot competition archery with my Dad...He was way deep in the weeds with it, but he taught me to shoot the same thing,same way every time. Do it the same, same it is easier to figure out what is wrong. Do have a CharliedTuna replacement trigger in my popgun. Was worth it...Gonna pass on the blue gun piston seals...Mine is doing fine as is, right now...Do not want to change a thing.
