k, so i was outside adjusting my hop-up, because i did take off the battery tray to see the gearbox and nudged the hop up while doing so, so i ahve that down, and i see what you mean by veering to the left, but there isn't a problem when you've got it at the right spot.
so here's my grouping at 85 feet
that target is about 12" in diameter. I'll let you be the judge here saying as though i don't have another rifle to compare it to.
