Looks like a very nice gun. As for the AR, without knowing specifics I can't comment too much on value, but you probably got less than it was worth. I bought one of the Troy ARs from Dick's for $900 OTD and sold it for $2,000 in January.
However, if you sold a gun you didn't want and bought one you did, you are still coming out ahead. Glad you're enjoying the new purchase.
