No I don't spend any time at AR-15.com.
I love my CAR, I carried one when I was an RTO - 1st ranger bat.
I once hit a moving target at 500 yards with it
...Not with one shot though.
Having shot literally thousands of rounds through the government model, I am fairly proficient with one. So I built one.
Mine is not fully automatic, other than for wasitng someone elses ammo, auto's suck. But they are lotsa fun.
They are not much good for home defense (shoot through walls, cars, neighbors houses, SWF tanks, etc), Not all that accurate(300 yards is about max), Not good for hunting (weigh about as much as a high powered rifle with a scope, but with a tiny bullet).
But damn it is sexy.
And scares the hell out of those damn frenchmen.
