LMT Enhanced Carrier vs Standard Carrier -- how to tell?

I have a bunch of LMT bolt carriers with enhanced bolts. Some of the carriers are also the LMT enhanced version and some are standard carriers. I am trying to tell the difference between the two. I have identified 2 different “models” but want to double check which one is the enhanced carrier.

Of course nothing came marked from LMT…

Can someone quickly tell me the major differences that I can use to identify which is which?

Thanks

OK, I actually figured it out. I found another brand standard and compared that against the two different LMT.

For posterity sake, the LMT enhanced carrier has a more sloped top back cut, and 3 holes instead of 2 on the front right side indentation part. Amongst other differences.

I think this is the easiest to identify and most obvious visual difference.
