Guy named Josh, (see title) operates Storm Werks. Lots of cool AK parts, stuff for AR180's, Daewoos and odd ball shiite.
http://stormwerkz.com/I changed out a part I had previously purchased from him for another one of his contraptions and had to cut grooves into the mounting screws on the old part since the lock-tite I had used wouldn't break free and I had stripped out the allen-heads. (made screwdriver slots with a dremel).
I contacted Josh and explained that I what I had done to remove the old part and needed to get replacement fasteners so the old part could be re-used. Asked him how much he would charge, how to go about ordering and paying (since this wasn't part of his regular ordering system) and gave him my address to compute postage.
Josh replied that he would just send out a few fasteners!
Cool stuff on his website, and great customer service.
