I've decided on a boyds tacticool for my hog hunter. They have a model which is already inletted for a DBM. Problem is, it is for a regular factory barrel. The hog hunter has a medium contour barrel. I'm sure I can open up the barrel channel, but how much will that leave on the sides? And, will any aftermarket bottom metal/mag combo such as cdi work or will I have to get one from savage? Thanks.
