I ordered a Yugo M70AB1 and I don't think it has a side mounted rail mount. I have also heard that Yugo's have slightly different specs so aftermarket pieces don't always fit. What are my options to get a picatinny rail on somewhere on the Yugo?
Drilling holes and pressing rivets.
If you want to mount a red dot, you could get an Ultimak or one of those aluminum quad rail handguards.
