Ok so I got this hop up for my jg g36c. http://www.evike.com/product_info.php?cPath=24_71_369&products_id=25814. But when I installed it and put the mag in the bbs would go everywhere inside the gun because the chamber wasnt reaching the feed port hole thing on the magwell. Its like its meant to not work. Im sure im doing something wrong. Does anybody have any idea what it is?
