G&G gr 16 upgrades?
i know this rifle is at 320fps. I am going to start a little project, i currently have a solid stock because i was planning on buying the battery cran stock so i do not have to re wire the gear box.
Now for the internals is there something i should upgrade? I really would like to make my rifle as good as it can get before i add cosmetics to it...
Edit - ok i'd like to order the systema m120 spring and it recommends i get metal bushings, there are so many which ones do i buy?
