MR223 differences b/w original A1 & A3?

[CJM]

What are the differences between the original MR223, the A1 and A3?

[elektrobug]

MR223 - take down pin in different location, not compatible with AR15
MR223A1 - take down pin moved, compatible with AR15
MR223A3 - ambidextrous controls added, compatible with more mags

Those are the major differences but here are also other differences. You can read the details about the MR223A3 here:

Thanks.

Just bought a lightly used MR223.

Are these differences the same with the MR308 series as well?
