Re: Good Lower?
That is a quality lower and should be fine for a precision type build, only things you may want to change would be stock ( maybe a PRS with adjustable cheekrest) and trigger if yours doesn't have the Geissele.Not required but they would be my preference, Also you may want to keep in mind that these two rifles are at opposite extremes, so just switching uppers doesn't really give you a good match with the lower.Personally I would build on a dedicated lower for that use.
