Good points brought out by(wheelgun 28).
When first issued to troops in the vietnam theatre
the M-16's we're not delivered with cleaning kits.
The thought that they we're "self cleaning" of course
was sadly lacking. Eugene Stoner was in fact the father
of the M-16. And leave it to the suits to change the cyclic
rate of fire and changing to a ball powder and you have a
recipe for disaster. I've owned numerous Colts, from A-2s to
Match H-bars and they have never let me down.
I'll always have a Colt AR in my possession.
