Am looking at a picking up a RI Tactical. I'm seeing where some are parkarized (Bud's) and some have a "black matte" finish (back ordered at Centerfire)....is the Black Matte one gunkoted or parked or something else....any general consensus on which one is preferred. I'm also seeing what looks like variant with some different sights, night sights or a hi-viz front sights for $100 more but don't see where the cost difference is justified. Can anyone point me to another wholesalers that normally stock these variants. Also, was considering a double stack A2 RI but no one seems to have them in stock anywhere....anyone know a source?
