98 Custom Cleaning

Ok so I must have thought I cleaned my gun and evidently I didn't. Last couple of times I went out I could not get my gun to Chrono over 240 or so even with velocity turned all the way. The first time I thought, well it might be my HPA tank. I played with it that time chronoed all the way up. I then went and bought the spring kit for the myth regulator and the next time around to my suprise still same issue. I played with my TPX and anyone who read my post knows I had a heck of a day with that too. Still had fun because I don't let things like this get in my way. Well today I got stung mowing the yard so I decided to put the back yard on hold until it cools down. In the meantime I pulled my gun apart and low and behold I must have not cleaned it the last time I played. It was all gunked up. Just took over an hour to clean. So long because while I had the whole thing apart I noticed that the inside was not very smooth. I thought about some postings boasting polishing the interior and thought why not? Grabbed some very fine sand paper and completed the task by hand. Let me tell you it is a huge improvement! I have not chronoed it yet but I know it is running way high now. Just a thought for anyone considering it, make certain you clean your gun and if you get a chance just sand the interior bolt section down. It may run a little bit more efficient now? Anyways just thought I would share!
