I did install what I think in the yellow green tip. Mine gun did not have but one tip when I got it, it was a black or brown tip. I called adams and they sent out a pack of tips. That pack only have 15 not 20 tips. Not that I complaining, but I am not sure what 5 tips where missing. I do have a greenish color tip. I think it is the green yellow that is shown on the card. But it could be the yellow tip as I don't have anything to compare it to.
I will give it a try this weekend. I will post tomorrow about how fast it goes through it.
