I am interested in how the number of countries FN was able to sell it product to means it was the better design? The rights to the M14 were owned by the US Government. Did the US even allow any of the private manufactures of the M14 to attempt foreign sales? Let face it none of the US firearms companies have even been very successfull making foreign sales on their own after 1920 or so.
Do you have anything to back that last statement up? Because Armalite managed to sell AR10's, a design presumably not backed by the Pentagon, to Portugal and Sudan, which admittedly weren't big deals but they were more than the M14 managed by itself, and Britain bought 10,000 AR15's before the USArmy adopted the M16.
As to your first point, I, and I think most people, would say if a product is being bought in the millions then it must have something going for it. Armies on six continents weren't buying the thing because of unrequited love for Belgium.
The T48 was a inch pattern design not a metric one.
That doesn't mean it couldn't be a selective fire version. IIRC the Dutch licenced version was semi-auto only and that was metric.
Did your friends tell you how the South Koreans in Vietman armed with the M16 didn't have any of the problems the US Army had with it?
From what I have read the USMC locked out the full auto function on most of the M14 rifles ii issued by removing a part. The FAL wasn't really a good fit for the Marine Corps. One of the moving forces behind rifle design in the Marines is the rifle teams. The sights on the FAL are no where near as good for match shooting as those on the M14.
So your point is what? The USMC rifle teams didn't really give a damn what the Australian believed. Come shoot division matches this year with me and talk to those guys.
Are you seriously telling me the USMC's primary concern in selecting a service weapon is how well it does in shooting contests?
