Keep the AR. Buy a used bow? Getting back into archery hunting, that was my approach. I picked up a new to me lightly used Reign 6 for less than half what it would cost retail. Being left handed it took awhile for the right combination of bow and price to come up. But I kept my mind open to many different brands and models and just waited for a good bow and price to show up. Have patience when shopping used and the right deal will surface.
Being an off road riding/racing dirt bike rider, I have a qualifying question when I get newbikeitis. Will it make me faster and or a better rider? Answer is inevitably "no". If my bike isn't a maintenance/repair needing time suck, and the answer to that question is "no", I end up saving myself thousands of dollars every couple years. Has worked for hunting rifles too. I can't seem to justify adding new rifles when my Dad's hand me down 1980's Remington 700 30.06 is subject to the same reasoning. Far more than adequate for its purpose.
Of course the latter is if money isn't available to burn! When the time is right and my finances allow it, time for a new toy!
