hey guys this is mt first post, a week ago i orderd my first AR, its the RRA varmit  EOP, my ffl dealer said it would take 4 to 6 weeks. heck im already sick of waiting. i orderd a mueller 8.5x25x50 for my optics. was wondering what the best rings are for mounting scopes on that gun.also the barrel is a 1:8 twist, what are several types of  off the shelf ammo i should try, ill be shootin squirels(spelling) so accuracy is important. ill be going to huge gun show in march so buying in bulk would be nice too.well is ther any other must haves i need to know about for my new varmit killer  damn i cant wait.   THANX FELLAS

If you shoot a tree rat with that, there is not going to be much left. And please do not shoot up a tree from the ground as a .223 round can go a long way.
