Re: How common are "slamfires"?
I can't say for a M1A as I have never shot one but I have had it happen with my SKS. I've found with the SKS that a very good cleaning of the bolt, firing pin, etc. does wonders to help prevent it from happening. It may be the same on the M1A. I will say that its a BIG suprise when the thing starts going full auto. Not something you want to happen when your not expecting it.
If all else fails, VOTE FROM THE ROOFTOPS
Trying to reform a liberal is like trying to pick up a turd from the clean end.
What this country needs is more family trees that will produce more lumber and fewer nuts!
