Hi there and sorry to hear of your problems, you obviously want a rifle so just tell them (dont ask) you want a refund or a swap for the AA4/510, they should give you the swap as they still get your money and the AA is a cracking bit of kit. I would not even touch the r10 if they hand it to you, be firm and fair but dont accept NO
The r10 never gets the shots claimed by the way
Good luck
Chris
