Hey guys I just bought a B&C m40 for my 12fv top bolt release not realizing that it was made for bottom metal and not blind mag. Totally my mistake for not paying attention. I have been searching for the past couple of days to find good bottom metal that wont require a bunch of inletting, but haven't been able to find a definitive answer. Does anyone know if the PTG bottom metal is factory DMB inlet or not? The only reference I could find was in this post

and all it said was it was still unclear if it was or not. I have not been able to find anymore information about. I emailed B&C about it and all I got back was that the m40 is setup for factory inlet. Would the accuratemag bottom metal fit the m40 without major inletting? Would there be an advantage to one over the other? Obviously some people will recommend CDI, but I wasn't expecting to drop this extra money on a stock so cost is some concern.
