All it has to hold is a 10 rd tube straight up, or a 45 round hoper. So temporary ideas involving pvc and super glue are fine with me. I thought about cutting off the top tube and then using part of it as a feed neck since its already the right diameter, just add a verticle elbow ala spyder xtra's. Later on I'll find the right torch or whatnot or maybe send it to a custom place.
