Yes you called her stupid or a liar. Since she's not stupid then you called her a liar.
I'm intimately familiar with the gun. She had enough time and training on the range that she should have had no problem. As I mentioned before, kids can do it. I'm also familiar with USMC trials and evaluation reports on the guns.
Others here with as much experience as you say it can jam before firing in dusty conditions because of closer tolerances.
When they post why, it will be meaningful; otherwise it's not.
Closer tolerances is what they said.
I've seen intellegent people who's brain didn't work at times. A failure to focus on the task at hand does not imply stupidity. A persistent failure to do so is strongly suggestive of it.
"before firing in dusty conditions because of closer tolerances."
Closer tolerances than what? The fitting of the firing pin is tight enough that no sand and dust would build up in the spacing to cause binding. Once cocked and loaded there are no other mechanisms that could get stuck resulting in a failure to fire. If a light hammer blow(dust) resulted in a misfire, it could be immediately cleared. Unless the owner allowed the inside of the reciever to fill with a significant amout of sand and/or dust, the shooter could clear it with one, or a few manual cycles.
"I looks like she is just humbly saying that she shouldn't have been labeled a hero out of respect for those who are the heros."
That could be, but this is the NY Daily News. Are they the liberal media? They said she, "angrily accused the pentagon of using her for propaganda."
