I looked at this earlier. It does look a tad dodgy but there are a few factors that should be taken into consideration such as the seller is blatantly selling guns which is in breach of ebay rules so its hardly suprising there are no pictures.
Also, If (hypothetically speaking) if I were going to buy this lot and collect it, I would sure as hell let the buyer know that if it would be payment on collection as well. Also I would be asking for a phone number so I could speak to the seller in person to see EXACTLY whats on offer.
So long as you take a few mates with you to pick it up, wheres the risk??
But as for bidding, paying by paypal etc.....Feck that
Cash on collection FTW!!
