Anyone in here know much about semi-automatic rifles?

It means it fires when the bolt closes instead of when you pull the trigger

I wouldn't worry much about a slam fire. There's a lot of internet rumors around, but very, very few instances of slam fires, assuming the firearm is kept in good condition. What freaks some people out is that the firing pin is free-floating. When chambering a round, the pin flies forward because of momentum, and will dent the primer. This is normal, and happens on the M1, M1A/M14, and M16, among other rifles. But the pin will not have enough energy to fire the primer in this fashion. You could in theory have a problem if you are using very soft commercial primers, but the likelihood is extremely low.

The most common cause of slam fires is poor maintenance. If crud is allowed to build up in the firing pin channel, it could restrict the pin's movement. If this happens, the pin can get stuck in a forward position, which could cause slams. It generally takes quite a bit of build-up to cause this, so just make sure you clean the pin and channel during your cleaning sessions, and you shouldn't have a problem.

Other causes tend to be poor quality ammo, or improperly reloaded ammo. If you reload, pay close attention to primer seating and maintaining proper bullet seating.

Of course, any mechanical device can fail, so always keep the muzzle pointed in a safe direction when you are chambering a round.

Now I know what you mean. I know exactly what you mean. Someone almost blew their brains out in basic training because of that very thing.

The M16 is notorious for it. All you need to do is slam the butt into the ground and it will happen, and that's how it happened to this other kid, but his safety was off when it was supposed to be on.

The M16 WAS notorious in it's early days, but this was due to a heavy firing pin. This was changed, and the problem went away. The situation you describe would not lead to a slam fire if the rifle was in proper working condition. Chances are, the guy had his finger on the trigger.

It was an M16A2. His finger could not have been on the trigger (unless he was holding it in a really weird way) because this was the "three to five second rush" live fire training. This drill sergeants were definitely on edge for this one. He got yelled at for a good while. He was the one poor kid that has no aptitude whatsoever for mechanical things like a rifle.

That rifle kicks fucking ass. Gonna leave it stock, or deck it out a la M21/M25?

Have you been walking around shouting "THIS IS MY RIFLE! THERE ARE MANY OTHERS LIKE IT BUT THIS ONE IS MINE! MY RIFLE IS MY BEST FRIEND, IT IS MY LIFE..."?

I'm gonna do two modifications to it.

1. Springfield Armory Scope. The thing I like about that specific scope, still leaves the iron sites available for closer targets.

2. Vortex Flash Suppressor. A little lighter (but it's literally ounces that go unnoticed) but it's the one used by our military. The flash suppressor on the gun now is great, the Vortex, even better.

As far as "This is my rifle..." I have been taking it apart, and putting it back together. I hope to be able to do it blindfolded soon.
