WTB: Unsingle Trap Combo for Youth (13 years old)

I have a 13 year old boy who competes on the local SCTP Trap team. He currently has a 686 silver pigeon sporting but it shoots pretty flat. We are looking to get him a more appropriate gun capable of shooting a higher POI. His current LOP is 13 /3/4" but he could easily stretch to 14". Please let me know what you might have that would work. I am also open to an Unsingle only or a mid to high rib O/U. Thank you.
