Hello, I dont know much when it comes to unsingles but I know somewhat for O/U shotguns. I am looking for a unsingle combo to get for my son to benefit him greatly for trap. Can someone point me in a direction? I am looking for something about 4000$ or less. Obviously no crazy high dollar guns but a MID-HIGH end gun for my boy. I am not purchasing yet just making a decision. I want to learn about unsingles. Please help with any recommendations or thoughts!
