So I'm contemplating clearing out a little space in the safe to focus on some of the guns that I actually shoot regularly. The couple that I'm looking to clear out are "built" ARs, with basic lowers and various LPKs, and pre-built uppers. None of them are anything special, and frankly I don't even know what I actually have into them as they were pieced together over time. They're certainly not "high end", and I'm not expecting to fetch any kind of serious money with them, but with the AR market coming back down to earth lately, I'm kind of at a loss on how to value them if I were to sell/trade them in, so I figured I'd ask if anyone has any experience in the matter.
