Hi, I purchased this from KYAirsoft around a year ago. I wanted to replicate my LE service weapon. I recently took the slide out and used a heat gun to remove the orange tip so that it would look as close to my service weapon as possible for practice. Since putting it back together the slide gets stuck at least half the time and I witness some interesting things like 3 bbs flying at the same time. This has left me with my Umarex G17 Gen 14 to practice my quals with. I have lubed all moving parts with Kroil to no avail. Any ideas what to do here? I have emailed KYAirsoft for pointers who is usually lightning fast at getting back to me but I have heard nothing back yet. Maybe I didn't put something back together correctly? Not so sure about that. I have probably taken it apart and put it back together 20 times now. Starting to wonder if it was always like this. I really didn't use it all that much prior to today....I doubt it though...something happened I think. Thanks.
