I am impressed with the input here & thankful.
Reloader,
I have been very fortunate to have been given the opportunity by Uncle Sam to be cross trained as an armorer on a whole host of weapons systems, including the M4/M16 series, as well as be the guy in the field carrying it.
I can tell you from spending many hours inside of many defense manufacturers factories acting like a sponge, that I have zero problem carrying a Colt M4 into battle,. The DI system M4/M16 series has served me well in some pretty lousy places, in some pretty austere conditions and has never let me down.
