I'm contemplating purchasing a DBM system for my rifle which is built on a Stiller TAC 30 action and pillar bedded in a McMillan A5 stock. Currently the rifle has a BDL type floorplate. Which manufacturer would be the simplest to install(Seekins, Badger, CDI, etc)? Would they all require similar work i.e. modifying the opening and possibly grinding the existing pillars to get the right height/fit. I'll probably have a qualified smith do the install/modifications when I rebarrel. Thanks.
