what method did you use to get a hold of him?I got a hold of him a few months ago asking about a Grendel barrel. It takes him kinda a long time to respond. Pricing for the conversion WAS around $200-250. Someone correct me if I'm wrong, but I don't believe the Creed will fit in an MRP. That's an MWS/large frame AR cartridge. MRPs are AR15 pattern.
