And I will add, piano wire come in varying sizes from something like 5 thousandths of an inch up to about a quarter of an inch.

The AK's I've owned(sadly not here in a disarmed Australia) indeed do manifest this curious wound wire as the trigger group energy.
The bolt recoil spring is not on appearance piano wire, but then Im pretty good on AK's not Pianos !!
I hear its also useful as a method of execution, but thats for another discussion in another place

I deliberately avoided mentioning that lol. But talking of executions, they hang actors by it, or used to, maybe they still do. But when they 'fly' through the air etc.
As for the AK, I'm not sure which spring it is, but it's always been a boast of piano wire manufacturers.

It is alleged that the trigger return spring in an AK/AKM is of Piano wire of sorts, but the bolt return spring is a coil, with a similar retaining spring inside that.
Directly under the thumb release section behind the dust cover is a long spring with some form of wound materiel inside it.
The trigger group has a smaller diameter wound spring that is pre-tensioned so as to return the sear to the lock position.
On full auto selection , the interrupter sear is engaged so as to prevent over run, acting like a rate reducer, to stop the rate of fire increasing out of control -to destruction.
The concept of the old L1A1 /SLR being able to "go full auto" is true, but that cannot be controlled as the base L1A1 has no interrupter sear, that came in the L2 with the heavy barrel and bigger mag.(early squad automatic weapon)
Yes, the L2 trigger & interrupter sear could be transplanted, but this was exception not norm.
That aside, piano wire I am certain has a bigger potential than we use it for in 1/16th tanks.

I was shown how to make an SLR full Auto by an Armourer (Remarkably easy) who reminded me that were I caught doing it I would be leaving myself wide open to a Courts Martial,
Like the saying goes, "A little knowledge is a dangerous thing".
