I had to go back and re-read the original post to see how it got to this point.
As the Subject states, The problem is clearly the Rami.
The RAMI seems particularly vulnerable to Frog Lube when it gets into the piston-type recoil spring assembly.
When the Frog Lube decides to congeal, it turns the recoil spring into hydraulic shock absorber. Plus, when it gums up inside a firing pin channel, it causes light firing pin strikes / misfires, but I found that true in an AK (of all things) as well.
Overall, I'd say that Frog Lube is bad for any firearm you actually intend to shoot (i.e. self-defense weapons). However, it works great if you want to completely rust-proof your firearm before you put it in long-term storage.
