No I definitely agree with you on getting a reputable gundoc to do this all for me so I don't screw anything up lol I have been contacting a few in the GTA area...

Honestly though I wouldn't touch anything inside the mechbox, stock it's a really good gun. If anything just get a new hop up unit, rubber, and TBB and it should boost the FPS by about 20 more or less. If you get really courageous then get new compression parts while leaving the spring stock. It will do two things, one you may get better compression and as a result better consistency and therefore a slight FPS increase as well as accuracy, and the second is that it doesn't add any more stress to the internals due to a higher powered spring.

Also keep in mind that the tightness of the barrel isn't the determining factor, it's the "trueness" of the barrel. If you have a barrel that's relatively straight vs one that's kinked in a few places the barrel that's bent will give you weird trajectories because the BB will bounce more inside the barrel while the "true" barrel will make it bounce less and give a more predictable trajectory. So just because a barrel is tight doesn't mean that it's better than a stock barrel. Get a barrel like PDI, EdGI, Laylax/Prometheus, and a new one that I've found to be pretty good which is Guarder 6.02 barrels (just make sure you swab it out to clear any dust inside the barrel otherwise it will result in BB's getting stuck).

PS: You also may want to get a ported cylinder in your "FTK" (EDIT: Stands for "Full Tune-Up Kit") because the barrel of the "Beta Spetz" is shorter and you should try to match the cylinder porting with barrel length.
