I thought I should buy some new bucking for my jg and So I took it apart to take a look and see how hard it would be to DIY it. Well... I'm confused within 10 minutes on something very simple I'm not sure what order this should go in. Can anyone help me out? I have here my inner barrel, hop up, bucking, and a little mettle ring and I think it should be barrel with the hole on top then mettle ring on it then bucking then hop up. Is that anywhere near correct?
