I just puchased a Rock River Ar-15 and have a few questions. It has the 1in 9 barrel and I always forget which ammo works best in these, 55gr. or 62gr.? Also is there a problem with using some of the cheap russian ammo in these like Wolf or Silver Bear? Thanks for the help........
Have any of you had problems with Thermold or any of the other synthetic mags. in these rifles?
