For the ppl new to Armslist, it is no different than any other online forum for buying and selling, there are, and always will be people trying to take advantage of others. This listing is a perfect example and has all the hallmarks of a scam. 1) A relatively rare, high dollar item, 2) No city listed (Arizona, Arizona), 3) No phone number listed, 4) Listings by user reveals 2 other relatively rare, high dollar items for sale - FN SCAR and Keltec KSG, 5) I haven't verified it with this listing, but about 9 times out of 10 you can find the same item with the same pics on GunBroker, GunsAmerica, AuctionArms, etc. IOW, the poster 'steals' the pics from a legitimate listing on another site. 6) Often you can find identical Armslist listings with identical pictures and verbiage in multiple cities and/or states.
These are just some I the things I have noticed that are common with these scam listings, others may have additional insight. When you see these, FLAG THEM..Armslist requires very few people to flag the item before it gets removed - I'm not certain what the number is but I think it is 3 - 5 unique 'flags'. Just my $.02...
