It's up to you but I sold my only AR15 not long ago, while I still could! I don't know if any forum members have more than one. I wonder why you never tried out your AR15 since I also got mine at the same time and paid over $1,500.00 for the same rifle, USED!. I did shoot it before I sold it though.....At a MUCH lower price than I paid for it! Don't expect to get get near what you paid but something is better than the nothing when they are confiscated!
I'm more of a bolt action and shotgun kinda guy anyway.
Scratch Nevada, they no longer honor Florida. I plan to apply by mail and need to get my prints done at my PD. I received a fingerprint card from Florida a few days ago. Open to any advice going forward, and wish me luck.
