M3M looks impressive but no mention of barrel replacement when over-heated. The old Ma Deuce has been a mainstay for generations but the barrel would begin to droop when over-heated, affecting accuracy.

Does not overheat as bad as the M2 since it fires from an open bolt. I'm betting it has an easy to change fixed headspace barrel like the M2A1s.

That's probably a safe bet.

So someone MIGHT have finally come up with a comparable system to John Moses Browning's M-2?!
