The M-16 was widely copied by the communists along with ammunition.
The ammo was sub standard and the brass casings would frequently expand in the bore and stick, and the ball ammo built by communist insurgents was too high in pressure often breaking even the real US production M-16s.
The standard production Colt with it's vanadium moly steels was durable. The copy was plain Jane steel and would pit, gall and even explode.
But the US sabotaged early AK-47 was worse.
Very early AK 47s used milled steel receivers. Because the round of the AK-47 is fatter, higher loads are placed on the rear of the cartridge. AND THE RECEIVER. When our commandos would switch their ammo these early issue AK-47s would KILL their operator.
Some "block" countries STILL produce AK-47 "influenced" firearms with milled receivers.
THESE are STILL vulnerable to tampered ammunition.
The AK-74 is a better choice. It has longer range, and it's round is less stout, so it places less stress on the receiver.
Ammo tampering is not new to war. It's been a covert tactic employed by various Armies for over 100 years.
The M-16 is actually LESS vulnerable to tampering than the AK-47. EVEN when it DOES get exposed to bad ammo the M-16 Design does not go boom, most of the time.
THE AK-47 will not USUALLY be fire-able after exposure to tampered with ammo.
The M-16 usually will, but only one round at a time, and that round will stick in the bore.
THIS is the oft used reference to "packed" ball ammo in military reports. Normally, one uses LESS ball powder. One doesn't PACK it.
We chose to keep moral up.
Odd I guess, given the race riots...
Why wouldn't we have just "given up"?
Those nice communists who would shoot an entire village, or run them unarmed 500 miles down a trail, give them a fresh uniform (their first) and an AK-47 with three rounds in it, to charge US machine guns, THEY were surely the BETTER ... what I'm at a loss for words... surely they aren't men.
Why would we lie about the number of spies in the USA? Mr. McCarthy?
