Would a 5.98 or something like that require more maintenance and lose the wide bore advantages, or would I be fine. Also, is the MR-Hop bridged or not and if you don't mind explaining, what's the difference. What length barrel do you think I should go (stock is 550mm I believe), and do you think I would be fine without the Action Army hop up for now. (I'm on a budget but I plan on getting it later down the line.) Thanks for your help.
