I got a chance to buy a new rifle on Ebay. That is in stock, now... That same rifle is backordered for 3-4 weeks. on all other airgun sites...The only hitch is , Itll cost me 113.00 more on Ebay, no big deal...Then I saw a post awhile ago here, that you should'nt buy rifles off Ebay...I cant find that post again...So just wondering what could be any major drawback to buying from there
