I recently picked up a DDM4 and have only put 30 rounds through it. I have been trying to do searches on cleaning and maintenance. I have found conflicting info about cleaning certain parts such as the bore. How do you clean your bore? Do you use a bore guide? Which parts are “delicate” and can hurt the performance of the rifle if they are scratched? How often do you fully strip and clean your rifle?
Did it come with a manual?
