I have a Mcmillan HTG that I need opened up for M5 bottom metal. Prices seem to vary widely. LRI 200.00. Unknownmunitons 125.00. Gap 105.00. Badger 75.00. Riversbend gun company 75.00. Trust badger but they specifically say their inlet is only for badger m5. I thought they were pretty much the same. Not sure I'm going to use Badger so that kind of concerns me. Was thinking Hawkins, maybe. Anybody got any recommendations or experience with the above or others. Want the work done well but don't want to waste money either.
