I guess I have one of the exceptions - a refurbed 1942 Tula with no PU grooves in a serial-#-matching late/AVT-style stock (i.e. beefier but only one safety notch) with a 12-port muzzle brake and early-style barrel band with the sling swivel.4 port brake is correct historically for 1942 rifle. 12 port is not correct with probably few exceptions.
I've wondered if it is worth taking the muzzle extension off, cleaning if necessary, and applying copper anti-sieze before reassembling, to avoid ever having to take it off for cleaning, but to allow for reliable disassembly if it ever needs it.
Regards,
