Just picked up a slightly used PSS with DM. Searching here I've heard that the factory DM system isn't that great. I've also learned that you cannot turn a factory DM into a BDL without a new receiver. So that leaves me with getting a new DM system (Badger, Seekins, HS, etc). Will an aftermarket DM system work on a factory DM receiver? I've searched the site and found a few threads that ask the question but no definite answers. I'm sure I missed something or mis-read. Been a long night and I wouldn't put it past me to fail to understand 2+2=4.
