There seem to have been a few more of these recently than is usual, and most by members with very few posts. This site, although a resource for the membership, is not intended to be either a poor man's 'Blue Book' or some kind of cheap (as in 'free') auction site just for 'drive-by' sellers. Some posts, although most are genuine inquiries, are in effect, 'stealth ads' posted to avoid the selling restrictions, and all have the potential to morph into ads posted outside of the classifieds.
In future, if you want to know how much to charge for your weapon when you sell it, or whether you paid too much at the local gun store, do your research at one of the many sites online that price firearms for sale.
Two that come immediately to mind are:
www.gunbroker.comand
www.gunsamerica.comAny posts that appear to simply be price checks will be deleted without notice.
