There are/were two versions. 2767-20 and a 2767-20A.I recently bought the 1/2 version....![]()
Unless you got old stock you should have the 20 with no A. If you do you are fine, the redesign died very quickly and you can think the internet for that one. It is a monster, and very well built impact, this is why they redesigned it to make it cheaper, and it busted left and right.
For your viewing pleasure. IIRC if you have a 20A Mil, will replace it free for you.
It is interesting that the "response" video is no longer available. Wonder what happened there.
