Have a (solved) problem with the M-16 and one with 5.56.
Lost 2 friends in ‘65 due to feeding malfunctions. One was a failure to extract completely and the spent round case jammed with the one feeding off the mag. It was during a shi storm and the 4 second delay was all it took.
Another was a round where the extractor tore the rim and bottom off the case.
Personally, my xm177 was fine.
Re 5.56, why not just “Bite the bullet” and just go to the 6.5 Grendel or the 6.8 SPC?
With your results, you’re a better shot than me.
BTW, one of the biggest problems in RVN was to train new guys to NOT spray and pray.
“Re 5.56, why not just “Bite the bullet” and just go to the 6.5 Grendel or the 6.8 SPC?”
Too expensive! The 5.56 is just fine. Inexpensive, accurate, etc. The kinks have long since been worked out.
That said the .25 x 45mm by Sharps looks interesting. I may get an extra barrel/Upper and load some up. I wouldn’t hold my breath though.
“Another was a round where the extractor tore the rim and bottom off the case.”
Granted, that’s why they gave the management of Lake City Ammo plant to Federal Cartridge Co. Been smooth sailing since.
I didn’t move around much. As a Radio Relay Repair guy I got to sit atop hills with my parabolic antennas showing the way to my whereabouts. A good defensive posture was a necessity. I never lost any friends. Tiger Mountain ‘68.
