Take Jerrys word on this one.I have one of the repo drums and
they work just fine.I have fround in my test they may have an
adavange over the real drums. The cutout for mag on these
is a bit high and will not let your hold open work after the last
round has been fired from your drum but that would only count
if you were in combat and hav another snail drum fully loaded
and ready to go.I found that with the notch on the repo I could
have a live round in the chamber I could put a fully loaded repo
drum in the gun with the chamber closed as long as I did not
unlock the winding leaver untill I had the drum locked in place.
This gave me 32rd plus 1 in the chamber for a total of 33rd.
I could not do this with a orginal drum as the notch on the tube
was in the lower position so the hold open would work on the
last round.I unlocked the winding lever after the drum was in place and was able to fire all 33rd with no problem.
