NO...

It's a combat weapon, not a friggin glass figurine...

In the Army, they get thrown around, dropped in the dirt, used as ladders, etc... And they work fine afterwords...

So long as she doesn't use it as a pry bar, it's damn hard to break an AR....

If it's GI-proof, it's girlfriend proof...

not sure how a MUD covered rifle helps this guy but whatever. Hey man my exgirlfriend dropped my browning .223 wssm with a Leupold 6.5-20x40 scope on it. That is why she is my EXgirlfriend.   I wouldn't suggest doing the same with yours tho (girlfriend that is)

Doubt it.  These rifles are designed to be used to beat down doors, shoot the hell out of Hajis and terrorists, and do so in conditions that are very unfavorable to smooth functioning of a firearm and they accomplish this.  No worries.  One good wack on the flash hider isn't going to hurt anything.

There's even a flash hider made intended to be used as a melee weapon; it has edges that will do damage if you jam the barrel into a bad guy's chest with it.  I think it's called the medieval flash hider, I forget who makes it.

Gives it character.  My first centerfire rifle was a Norinco SKS, which I still have.  It's traveled far and wide with me.  She now has scratches in the stock, spots with the finish worn off, and some rust pitting on the barrel from exposure to the elements.  It gives her character

I'll probably get banned for recounting this joke that comes to mind.
A female flight student was having a horrible time, just could NOT fly the airplane, she was to rough on the controls, just could NOT keep the airplane trimmed and flying smoothly.
One instructor decided to take her under his wing and put in the extra work to help her make it through the program.  In the briefing before the flight he explained to the young lady, "You have to be gentle with the control stick, you have to coax what you want out of the airplane by gently manipulating that control stick.  Treat the stick like it was your boyfriends penis."  The instructor could see a twinkle in the gals eye, she looked as if she had an epiphany, so off to the aircraft they went. After take-off, the instructor turns over the controls to the student, and he pleasantly surprised, the airplane is flying marvelously, she performs every maneuver flawlessly.  The Instructor comments, "This is marvelous, you doing so much better."  The reply he receives back, "An-ooo, iiir, ooo-rre, a-iie, iii eally orking."  Wondering why his student is speaking so funny, he leans around to peer at the seat behind him to find the young lady with head down and over the control stick.

Yes, I'm going to hell for that one.
