Anything is possible.
When training the Thai Special Forces Recon (Rangers), they carried M16,s (I mean M16,s) that had ALL kinds of local modifications. Fishgill muzzle brakes, the works.
They also carried liscensed G33,s with all kinds of local made stuff, like scope rails done to LO-TEK 1913 specs!
I ended up getting some fishgill units, and few 40 round G33 Thai made aluminum mags. They would not DREAM of using anything smaller. Our Beta-C mags almost started a riot.
Those guys would parachute out of hot air balloons to save fuel costs.
We were about to get on one of their Vietnam era Hueys for a lift, when some guy from the U.S. Embassy said NO American will fly in a Thai military aircraft, period!
I was pissed, but then I was young. Now that I am older......
