I'm late to your rodeo. Just found your post. There are gunshows in the K.C. area where I have done very well selling my stuff. Depending on how much you have, renting a table might be worthwhile (I sometimes rent two). Enjoyable way to spend a couple of days and you can haggle for best price. No legal hassles and no messing with shipping, long distance buyers, etc. I do them for fun more than anything else - talking to other gun nuts is mostly a hoot. Good Luck.
Look on Gunshow Trader website.
