Edit: Can anyone confirm whether or not the MKM buffer lock is the same as the LM4? I'm wondering if I should get an extra BBA steel lock while I'm ordering one for my Magpul.

Yep, Buffer Stop is 100% the same.
I replaced mine with the BBA Steel Buffer Stop, perfect fit

I bought 6 as I prefer the look of these to the standard mags, but keep having problems with these locking the bolt back, even with a full mag.
After comparing these space between the top of the mag and the bolt stop lever, the standard mag has a shorter stop lever than the pmags. From measurements, there seems to be about 0.7mm difference.
So in theory, if this gap is enlarged on the Pmags, they should work as well as the standard mags. Has anyone tried this before or at lleast know if this seems a sensible thing to do! I would rather mod the mags, and keep compatibility with standard mags.
There are also quite a few videos on modding the bolt catch on the LM4, what does this fix on the LM4?

We found a simple and effective Fix to get the PMAGs running stable in the MKM
The PMAG (so also the Disconnector) sits a tiny bit higher in the MKM as the the STANAG Magazine!
So the Magazine Disconnector Part No 16 pushes the Bolt Catch up too soon after every Shot and not when the Magazine is empty
See Magazine Part No 16 Disconnector here:
So simply shorten the Disconnector 0,6mm where it meets the Bolt Catch, now your PMAG will work perfectly fine, Bolt Catch hits after last Round as it should
To disassemble the PMAG Shell unscrew the Bottomscrews 25,26 and push the Magazine out of the Shell
Then take out the Disconnector No 16 and file down the small square Top with a File or Sandpaper
Also the PMAG fits a little bit more loose in the Magwell, but that is no Problem over all, i ve seen Real Steel Lowers with looser fit
Sorry, my English is very bad
