quantity of rifling grooves in circa1988 m16 standard infantry issue

[robertcolorado2009]

Ok, guys, I have asked a few questions about the info my work partner has said about his m16 when he was in the army during the 1st desert storm involving Kuwait. He says his m16 had only one rifling groove in the barrel. This is the same guy who said his barrel was bent and that the barrels were so worn that the bullet actually bounced on the sides of his barrel. So, I can't seem to find any info about the rifling in the barrels in that time frame. I can't wait to hear feed back about THIS! :-) This gets to be a little fun to be able to quiet him down when I get the REAL answers from you guys!

This is one of those cases where I didn't even need to be there to know that he's wrong...

Believe it is 1/7 RH twist 6 groove in the A2

If you were front line you had the A2 that was only a few years old. If you were support then many still had the A1. Many of my guys were expert with the old crappy (sarcasm) A1's leading up to DS1. Unit Armorer 16 mash 89-91.

BTW, your boy is full of shit.........

I heard they had to run a patch down the barrel at every mag change. Something about the groove getting leaded up from the rounds rattling down it. If they didn't clean it out, it would plug up and esplode.

Sounds like a carpenter blaming his tools. Or a tool blaming his tools.
