Just read a post that said the gun vender sells rare fusion riffles at 11:00pm every 3 days. Now the post was dated 9th oct and it said the vendor would be selling that night. So if my maths is right. 9th,12th,15th,18th,21st,24th,27th,30th,2nd then today 5th and onwards. Hope this helps or does everybody already know?
