You might want to check on that...Dlask just went through this by offering up the Colt M4 30 round mags (in .22LR) for their HK416 pistol (also .22LR)...they were told no problem.
That would not be consistent with the BX-25 ban rationale...
Why do you think the BX-25's were banned??? Because you can't have a 25 shot capacity mag in a pistol... there is no differentiation between centerfire and rimfire in this regard... they do differentiate between CF and RF long guns.
This is definitely not something that I would want to leave to the interpretation of a field officer.
