They have become my favourite weapons in this game. You can fire so fast down the scope, and enemies don't stand a chance if you have some distance on them. Plus i'm on the pc now and I have the WMX mod, so I can silence it, add a extra clip and an improved rifling attachment that gives it +12.5% damage. I just did the Black Mountain run at lvl 20 and the super mutant masters couldn't even get close to me, at the check points. You can put 4 or 5 armor piercing rounds into them before they even see you.
Not to mention these guns look friggin awesome!
Anyways, thats my new found love, rant for the day.
