Am I at risk of slam fire?
Firing pin is clean, unlubed.
AR is unfired, got the upper this monday.
thats normal dont worry about it
Alrighty. I was thinking that something like this might happen when I took apart the BCG and noticed that there wasn't a firing pin spring or anything.
I would still be careful when chambering a round. Never know when you'll get a sensitive primer and BANG!
You see that on some factory ammo. It is to insure there is no high primers or something. When you see something like this on something done with a progressive press it means that there was a powder flake or some other crud on the rod that seats the primer. Again not a issue.
It amazes me how durable primers are. I mash them pretty regularly on my press and they get crushed ugly. Bent in half, and mangled. They don't go off unless hit with a firing pin.
I think it's Federal ammo that's known to have slightly softer primers than others....
I could easily be wrong though.
Small dents like that are nothing to be worried about, though; all US semi-auto military rifles (M1, M14/M1A, M16/M4/AR15, M1 Carbine, etc) have free-floating firing pins, which leave little dents like that on chambered rounds' primers.
With decent ammo, it's nothing to worry about--though some people rotate the top rounds in a mag (if they keep the rifle loaded as HD weapon or similar) to prevent a cumulative effect on the primer(s), which may result in an AD (a true AD, not an ND).
If you actually shoot your ammo, though, it shouldn't be a problem.
QFT. Its normal but it should also serve as a reminder to have your gun pointed in a safe direction at all times, including when you chamber a round at home.
