Problem: magazine comes unseated/dislodged/drops after firing several times.

Given:
-problem occurs with all variants of mags and drums.
-it is an early model AR47 (one of the first 100 made)
-I heard that there was a mag release design change for the ar47 on the later models
-I heard that there is a way of modifying the back tang of the mag to resolve the problem.

Questions:
-what was the exact design change of the mag release? (Exact dimensions would be nice)
-what are the exact dimensions of the back mag tang modification to resolve the problem?

Here are some pics for reference and inspiration....

Sir, I do not have a solution for you.

However, may I ask if I can use the image of the receiver markings you have posted  in my receiver rollmark gallery?
I will post it here with the other 180 receiver marking images I have collected and give you photo credit if you do not disagree.  

Thanks

AR-47......interesting.

You just might have a collector's piece there as I bet there won't be many more that say "AR".
