Get I had an r10 mk2 upgraded from my s410, it lasted a short while and 2 trips back to BSA and they still couldnt sort the thing, pile of crap mine was, so I upgraded again, a hw100s, well it was ok, I like .177 but the only pellet it would shoot was bis mags and I couldn't get on with that out in the field as it was too damn heavy, so I upgraded again, to a pre at s410, may just be me but they are the best rifle on the market and are an all time classic,
