I did say I was new to airsoft but I've been shooting for years. I know I probably don't NEED a barrel but I would like one I i think it may help. I definitely has the symtoms of needing a H hop up or something like as the Bbs seem to fly true for a while, then seem to veer off up and to the left. Me and some of the gents at my airsoft club have had a go a the hop up and I think we have got it best it can be. Any ideas where I can find a hop up upgrade for the KWA g36c? Or even an extended barrel ?
