Is it armor piercing? Just what is the green tip all about?

No, it is not armor piercing. The green tip is to distinguish the ammo from the older 55gr M193. 1:12 barrels cannot handle M855 so M855 is emergency use only in those rifles.

What Brad said.

Also...
The US Military uses black tip to visual identify Armor Piercing ammo.

5.56x45mm M995 ammo has black tips.

The Green tip SS109 ammo has a small steel insert in the tip to help with penetration. If you push anything fast enough it becomes AP, although PHYSICS is fun I am not very good at it and can't explain the nuts and bolts of it. One day take some steel plates out of differing thickness and shoot them with a .223, 3006, 308 and 3030 and see what they do. I have been surprised at what a 55 gr fmj will go through...........

I used to punch threw old tractor block out at the farm as a kid. With some Nebraska national guard ammo. Dad got a couple 1000 rounds off the range in the late 70s early 80s.
I have no doubt it will punch threw 1/2 inch boiler plate.

It's 'Penetrator', but not 'Armor Piercing'

It's almost the same as SS109, But has a steel insert/lead core instead of tungsten/copper (?)

Tip color code IIRC, green for penetrator, black for AP, Orange for tracer

Yep, what these guys said. XM855 is 62 grain as opposed to 55 grain m193. The steel tip and insert as well as the additional weight of the XM855 is intended to aid in penetration over longer distances when compared to the m193. The jacket is still copper and the rest of the core is still lead.

Hope that helps!

M-855-A1 is the new "green" round, the M-855 is steel & lead.

NO Kiddiin... I embarressed the heck out of same sales reps from Dupont years ago that brought some Lexan samples down to the range to try and sell to the city..They said it would stop a 308 AP round,, and it did.. I told them I could cut it with one round from the smallest gun Remington made... they laughed and said be my guest...

One round from the .17 Rem I had in my truck shut them up... burned smooth through it..

.High Velocity 22's (22-250, .220 Swift) close in, will cut 3/8 to 1/2" plate that .30-06 and 308 just dent or bounce off of..

Speed kills, or in this case will punch nice little holes in tough material.

I have been surprised at what a 55 gr fmj will go through...........

As have I. The larger, slower AK round won't do this. I have to use AP for it to go through a steel plate. The 55gr FMJ cuts through it like it's nothing....

What other people said. It's maybe best practically described as "semi armor piercing" since it is built to aid in armor penetration. On the other hand, ATF hullabaloo about AP ammo importation does not apply to it, so legally it's definitely not considered AP. (And as other people have noted, it is distinct from actual military AP ammo.)

I was under the impression that the steel penetrator was just intended/useful for gaining a small amount more penetration after the rest of the core fragments?

I picked up some PMC 5.56 green tip when it was cheap. Haven't shot it, but PMC ammo is always good.

The green tip was originally to signify SS109 to differentiate from M193. Now it effectively signifies any non-M193 ball round. And as stated above, while it does have enhanced penetration over the M193, it is not AP.

It was built with the requirement of penetrating a standard NATO steel helmet at 600m.

It is not what the military calls "AP" -- that is the black tip, as has been mentioned. But it doubtlessly is capable of penetrating some types of armor. It would certainly penetrate about any soft kevlar vest (as would most any rifle round of intermediate or greater power).
