The search function isn't working and I am doing some research in reference to work. Does the M-16/AR-15 family of weapons have a drop safety? Thanks in advance.

There is no drop safety. However in stock form the rifle should be able to take a drop w/o firing - I stress 'should' there is always a possiblity.

From what I can remember while I was in the Army using an FN M-16 A2 if one dropped the rifle and if the bolt slams forward it will fire. Granted we were working on concrete and doing drills at the time but it wasn't THAT hard to get the bolt to go from being back to being forward.

There is no "drop' safety incorporated into the design.

The inertia of the firing pin can detonate some soft primers (223 ammo) when the bolt slams into battery. I've never seen it happen, but have read some accounts of it happening. I suspect incidents like this will increase with the increased use of the weapon platform by the LEO community. My department for instance, still issues Federal .223 ammo mean for varmint hunting.

I probably should have added this in my previous post but my FN issued M-16 A2 was a peice of trash. After the bad extractor was fixed it then would use a 2 round burst in semi-auto mode. The bolt moved forward with enough force to set off GI ammo.

Wouldn't it go cyclic? I mean if the bolt closed with enough force for the firing pin to strike a primer every time you fired semi, it would seem that it would continue to do so until you were out of ammo, not just once.

I guess it's all academic since you refer to the rifle in past tense. Did it ever make it to the armorer, or were you stuck with it?

The 2 round burst problem is more likely out of spec/worn internals. This was happening to me, and KEN and S.A.W. fixed it by replacing the SEAR and Hammer, I beleive.

I doubt the bolt movement would "set off" the round.

That's probably it. I know there were two things he replaced.
