Back from the range today, really wet out with some drizzling and a bit cold.
Tested the one rail on my 7.5" compact 7.62x39. Ran about 100 or so rounds thru it. Had roughly 4-5 malfunctions.

A had few others that were similar to the above pics but just by habit cleared them ans kept firing.
Rail held zero perfect for me and i dont notice any "scalloping" or wear to the rail in anyway.
Just wish we can figure out a way to get these stoppages fixed Magwedge. I really do like this rail ALOT.
