Wondering if anybody out there has a strong opinion on Ear height and spacing for a Protektor DR bag to be used with a Tooley MBR stock. From what I have been reading, you want the stock to run on the ear sides and not the bag surface, so would a 3/8" wide space be the way to go? Med height ears? I have a Protektor front bag with the 3m slick stuff on it- Do I want the rear bag to have the same material? Thoughts appreciated!!
