I saw something on negaive airsofts video's that i thought was pure genius, my arp9 is my cqb gun but i like to use it outdoors as well so im getting another barrel and hop made up with a 200mm barrel for outdoors and keep the 128mm for cqb.
I need a second hop unit for my arp9 but it's a fussy eater and will only feed reliably with the g&g rotary and not the ZCI rotary i have and I cannot find another g&g rotary in stock anywhere so I'm wondering if anyone either has knows anywhere that has some in stock or has a spare that I could purchase or if they know of any other hop units that feed reliably in an arp9
