I had an experience with an AR15 I bought from a LGS with whom I've done business for decades. They bought a collection of (stolen) guns from someone and local law enforcement was on the trail. I got a call from the store manager asking if I still had the rifle. So, the deal was they would give full credit including sales tax on what I paid for it, but it had to be turned in to them. I didn't have to deal with the cops at all. I actually ended up with a higher quality rifle they had in stock as a result. Sh*t happens.
