I just recently got back into paintball (last December) and my buddy and I have been playing a lot recently. My friend had been picking up quite a few used markers. One of his finds was a used RT. It had a slight leak down the barrel. Since he didn't have time to mess with it, I agreed to look at. Neither of us have any RT experience but I love to tinker. I thought this was going to be an easy replace the o-rings, clean and lube it up kind of job. Which, for the most part it was. I tried multiple o-rings one at a time and the valve REALLY needed an internal cleaning. The last thing I replaced was the power tube o-ring and it stopped leaking and was shooting much faster than I expected it. The RT is advertised at 6 BPS and although I didn't have a chrono to verify, I'd say it was closer to double that. After about 300-400 shots, the tank was running low, I took apart the marker and found that the sear was worn down at a strange angle and had started to ding the bolt a little. To be honest I didn't look closely at the sear before I started the project but I am almost certain the strange wear pattern wasn't there when I started. I just received a replacement sear from Tuna and I want to make sure before I start up this little project again that I won't be destroying a $30 sear. Do you think the original sear was worn and/or weakened? There isn't an adjustment to the sear. The body was attached to the rail tightly. Is too tight bad?
