The cheapest I use to buy SKS for was $49 and get a free case of ammo with them. AK's were $59 with the ammo.
Down south the hardware stores had barrels of Mosins for $25 and K98s for $35.
About 10 years ago I bought a pair of Polish M44s for $60.
My home defense pistol is a high capacity Russian made Makarov in .380. I bought in in the late 80's when they had to put an adjustable sight on them to import as "sporting". Got the pistol, 2 mags and a holster for $85.
Back then we never put any thought to the concept of them drying up.
Never thought you couldn't go to any hardware store and buy all the .22lr you wanted on a whim just to go shooting. A penny a shot was what the hardware stores sold them for or $4.50/brick.
But I would have to mow 1.5 yards to get that $4.50...
What makes these so desirable? I've got a russian made sks with the bayonet and original box. Maybe I'm just out of touch
