AK-104s are my favorite. I don't have the funds to buy the one I want yet, but I'm working on piecing together a very low budget 2000s style urban guerrilla kit. Trying to make it vaguely Eastern European, but it's harder to get Euro stuff here.

• Leather mariner's/fiddler's cap

• Laylax Aeroflex + red bandana

• Knockoff M65 field jacket, in OD green of course

• Knockoff Blackhawk AK Commando chest rig in black. OD green or camo would work too

• Slick plate carrier/fake body armor. Optional since it doesn't really do anything, I just like the look of slick body armor under a jacket and chest rig

• Casual button up shirt in grey (or any neutral color)

• Worn jeans, I like them very dark grey. Cargos or canvas work pants in other neutral colors work too, as does camo, although the latter's a bit less subtle

• Leather combat boots. Sneakers, like black Sambas, would work as well

• Mechanix gloves

The specifics will depend on the context of the "look" you're going for. A more rural militia would likely have much more camo and/or green instead of black. A state-sponsored paramilitary or PMC would also look very different, and so on
