Cost per weapon isn't really that bad although $100 for a muzzle device that's machined out of about $.50 worth of steel is a bit hard to swallow. But just like everything else if you want to play you got to pay.
I'm leaning towards the ASR system but would like to hear from someone who's actually used it for their thoughts.
ETA: Just saw this after I posted my response. Thank you for the input.
