Bent nail M16 front sight. Just what in heck is that??

Not enough info! As above or are you referring to the sight itself? Fiber optic thingie? actual bent nail? Need clues...

Found out it is a homemade, persay, sight tool and cleaner

The M-16 Bent Nail sight adjuster Club

I had a feeling that's what it is. I saw in a M-16 manual somewhere about fabricating one. I have one in my shooting box before I finally bought the proper tools. A-1 and A-2 have different prongs.

Field expedient sight adjusting tool. Circa 1967, we used 55 gr bullet.

The U.S. Army has finally started recommending NOT using a nail to adjust the front sight on the M16-family, FWIW. They finally acknowledged that using a nail damages the sight post, and scrapes the finish off of everything that it touches. A bit late for most of us, I'm afraid.

An FMJ bullet works well. As someone has already said. Well, I guess I should say a cartridge with an FMJ bullet.

so , just how often would one need to employ that tool ? i have the 'official tools' and only used them once ...so far , i do always shoot the same ammo

The proper tools fall into place on the range during recruit training. Not as much for the regular guys except if weapons get switched up. When you take a crew out for the group and zero...you end up adjusting everyone's sights...sometimes several times. Tools help.
