New Hunter
I'm brand new to this scene I really want to get into it. But I got questions of course. I know the rubies isn't a helmet to join a group with, it's mainly for my twitch channel. I will eventually either build my own or buy a mold/casting off of here. But nevertheless my questions are about the rangefinder for the rubies right now.
