Zastava M59/66 SKS 7.62x39 Semi-Auto Rifle, 22 in Barrel, Grenade Spigot, Matching Serials, IAI Knox TN Import
This Yugoslav Zastava M59/66 stands out as a correct, base-configuration SKS-pattern rifle with its 22 mm grenade-launching equipment and manual gas shutoff. It features matching serials on the receiver, bolt carrier, and stock, and is import-marked by IAI, Knox TN. The milled steel receiver, blued/phosphate finish with bolt and carrier left in-the-white, and 22 in barrel round out a classic M59/66 package.
Built by Preduzece Crvena Zastava (Red Flag Factory) in Yugoslavia, this rifle retains the factory M59/66 setup without night-sight flip plates. It includes the correct flip-up ladder grenade sight and a ported 22 mm spigot, with a manual gas shutoff at the gas block. A small square inspection/proof mark is present on the gas block, consistent with Yugoslav production.
The operating system is the proven SKS format: semi-automatic, short-stroke gas piston with a tilting bolt. Feeding is from a fixed 10-round internal box magazine designed for stripper-clip loading. Sights are traditional military iron sights, with a hooded post front and a tangent leaf rear graduated to 1200 m for versatile use.
Furniture includes a one-piece hardwood stock with an oil finish, finger-groove fore-end, and a ventilated wooden upper handguard with three slots. A rubber buttplate and rear sling swivel are fitted. An integral folding blade bayonet is installed in the correct M59/66 pattern. Overall, it is a full-size SKS-platform rifle with a 12.5 length of pull.
