First, let me say that this is an excellent product for the price. I am very happy with the Disco, probably because a little TLC rewards one with an amazingly competitive rifle.
But, I can't imagine factory tolerances would allow a gun to print 3"+ 30 yard groups, especially with the same company's best (and very good) pellet. I have not pulled the barrel to inspect it, that will have to wait till after sunday's FT match. (my boy's rifle) But I'd bet it's loose enough to nearly let a pellet fall through. That, I view as a QA shortfall.
