The BAR sucks because .308s arent sold in mass quantities (40 per vendor i think.). They are even harder to find in the normal Mojave. (Strangely, they are quite common outside of the normal non-DLC area.) i use Christines COS Silencer Rifle for my long range kills (as the AMR has a ton of recoil and doesnt suit me very well), and my silenced .45 AP for those close up sneak-attacks. For my mid-ranged gun i use Elijah's Advanced LAER..
