I hate to ask this cause I'm sure I'll be embarrassed once I get the answer but I couldn't find any reference to this in the user manual, online or any youtube vids so far.  I've had guns over 50 years but totally new to AK-47's .   The safety lever has 3 positions (2 indents plus full up which is Safe) and 3 letters.  One is marked 'S' which is 'Safe'.  One is marked 'F' which is 'Fire' but what is the one marked 'A' ?  

If I'm not mistaken, it's representative of the Russian words for "safe", "auto" and "semi".  Marked that way like the true military versions, in the order that a full auto AK selector switch would work.

Thanks for the ideas on that.   I did wonder if that was some reference to 'Auto' but of course I knew it couldn't be full auto fire.  It will fire in that position so maybe just a bit of nostalgia to make it look  like the original versions.   Pretty much what you said...

Correct.
Makes it look cooler, but even in A, will only be semi.  Like having safe/semi/auto on an AR with three position selector, still only semi.

Thanks for the confirmation.
