I'm extremely new to the LR thing and I am setting up an R25 to hopefully hit targets at 1000 to 1200yds. I'm trying to decide on a level for the rail. There is very little talk about these. Is that because I don't need one? If you guys aren't using one then how do you know you are level, and you're able to trust your adjustments? If this is a stupid question please be nice. Like I said, "I'm new here".
