You need to consider the options that defiance offers including straight or swept handle and port length for example. We get short and long deviants as a direct drop in for a Remington inlet (except for the side bolt release for composite stocks). Deviants cannot have side bolt release set above the stock line because of the facets on the top half of the action. I'm sure McM will do a "Deviant" inlet, but they would have a few questions on the specs of the action. I would stick with the R700 inlet if the handle is swept back, but I have used surgeon inlets as well with a little modification
