Well from what I have learned from my trail is that it can be a huge PITA. That being said it is one if the smoothest and most accurate springers I personally have shot. There is a lot of hate towards the trigger, but I have had no problems with it. My quest for accuracy started the same as you, but I came across a few threads in forums noting the crown of the barrel. Apparently there was some manufacturing defect and not all barrels were cut perfectly square, which means air wasnt escaping exactly the same after every shot. So I proceeded to file the barrel, VERY carefully as to not remove very much material but to ensure a perfectly square end. Once put back together I applied lock tight to the pivot and stock bolts. The hardest part I found was maintaining my artillery hold in the same position, the cheek weld didn't seem to matter much, but it does. After some practice and a hundred rounds I was shooting 1/2" groups at 50yds and sub 2" @ 100 yds. Best part, NO random flyers. None. They had me steaming mad but after the crown adjustment and practicing my hold they just disappeared. Havent had a flyer since, unless it was shooter error. Thats my experience so far, hope it helps. It will never shoot exactly like a pcp, but that's what I love about it, plus it adds way more to the satisfaction factor imo.
