Yeah, I'm a complete noob, this is the very first airsoft gun I've purchased. I've never even played. And from my research it seems wise to fix the issues that it has out of the box to make it reliable. I've already taken it completely apart and shimmed the gears, changed the piston, piston head, bucking, corrected the angle of engagement a bit, and I'm waiting on a new air nozzle to come in the mail.
Things I've noticed so far: the selector switches were both loose. The magwell screws were very loose and one was screw head was slightly stripped, The piston's teeth did not appear to be spaced correctly as I changed it out to a Modify I compared the two and the teeth on the stock one were not consistant in there spacing....the modify one felt a lot smoother on the gear too. The Cylinder itself appears to have a seam inside it, that is not chrome plated, you can see a brass line down it. It feels smooth to the touch though. The fore grip has a little bit of play front to back. I wasn't impressed with the sights it came with, the rear one seems to be a little pliable almost.... just didn't make me feel like it was very sturdy when pushed on. I haven't pinned it down yet but I'm pretty sure there is some inconsistancy in the sealing/compression area.
So as I'm doing all this, I'm thinking that I'm going to need to replace a bunch of the internal parts as they just don't seem to be very good, especially the air seal/compression parts. So if I were to buy a kit to replace these parts would I just buy a version 2 piston/cylinder kit? Are they all the same, as in not gun type dependant?
Originally I purchased a PTS ACR from EhobbyAsia and it's been stuck in customs inspection since 12-24-11..... and EhobbyAsia is not responding to my emails about it. So I found a new one locally and bought it.
