It is an FN development, who two years ago, also affforded me the opportunity to fire an M-2 variant they had souped up to 1200 rpm.
That may be what drove the QC barrel invention.
My favorite QC barrel mechanism is on the MG-42/MG-3.

Dont know when the QCB variant of the M2 was first introduced but i have it on my 86-87 Janes IW edition.
Yep, the MG42/MG3 is a great design..
