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.Alright.
If you want 500 FPS you'll want that cylinder, and a big spring, or HPA.
For barrels, I have a couple.
ESC Works 5.98X???
Grizzly custom works 5.98X???
Action Army 6.01X???
Abd for buckings, the 2021 85° MR-hop is good.
For chambers, get the Action Army, and for a nub I would suggest the MASADA nub.
To put in a shorter inner barrel you just need barrel spacers, which you can make by wrapping painters tape around your inner barrel
