Thanks for the heads-up. I might pick one up, but $70 for something that I would be hesitant to shoot is a bit much for my budget. Might be different if I didn't already have an aj stocked 1938B that, BTW, has a spring preload spacer and drilled out air tube that gives it 325 fps average MV. On that gun I added a windage adjustable rear sight blade from the 901 (137970-000 sight group, $1.75 each) and even sprung for a metal lever from Daisy (169862-100 Die Cast Lever, $3.00 each). I'm guessing the adult RR still has the plastic lever, else they'd advertise it was metal. The plastic lever is a pet peeve of mine- the single worst thing about the new style guns; even though it's proven to be durable, it's just cheesy.
I bought the Chief AJ kit but did not need the longer stock(I'm 5'8") the large loop lever though is a wonderful thing
