I shot a M-240, it was awesome.
One time expensive though.
We visited the son-in-law (Ranger/Airborne) and our daughter in Ft Benning for some sort of post exposition/celebration. Lots of parachuting, helicopters, missiles, military type stuff. They actually had a demonstration area that you could shoot an M-16 and M-240 filled with blanks, both in prone positions. I’ll never forget the image of my wife spread out behind the M-240. I’ve got pics to prove it! Fun day.
