Ive owned a bunch of them, I kept my milled Bulgarian sam7r and hungarian underfolder. The norinco mak-90 will forever hold a special place in my heart since one was my first. Love the 7.62x39 cartridge for what it is and the $/rd. Beautiful guns, rugged, reliable, all that stuff. Don't care for the selector switch or rock in magazines.
The selector switch is something isn't it?! LOL I can see both sides of the coin but it certainly seems to have been afterthought and could use a little refining! The OCD in some of us hate that damn scratch is leaves! LOL
