Not sure if this is the right place to post this, so apologies in advance.
I just finished and passed my CFSC and CRFSC course. We were taught the following to PROVE that the gun was safe:
1. remove magazine(s)
2. engage safety and keep it on if possible
3. observe feeding path/chamber
4. Observe barrel (from the breach)
And my personal favourite:

5. Observe bore from the MUZZLE (when observing through the breach is not possible) with a bore light.
Is this the right procedure? I was taught to never EVER look down the barrel of a firearm throughout airsoft from the muzzle and then they tell us to do this with real steel?
Apparently these are the CIVILIAN procedures, and completely different from MILITARY procedures.
What are your thoughts and opinions of this way to PROVE it is safe? Does it make sense, or is this just the routine "true" but "bad" way to verify the barrel is clear that is later taught again in a different way at gun clubs and such?
