If your rifle looks like a german k98, with a short handguard in front of the rear sight, it probably is. The Yugo's reworked a lot of k98's post war and ground the receivers (usually, but there are exceptions still wearing German codes/dates), stamped their crest, and the name of the rework facility (as in Preduzece44) on the side of the receiver. Does your say 'mod 98' on the siderail? If so, it's a k98 rework. Their reworks are usually good shooters, as they rebarreled all of them (8mm), and a lot were restocked.
Pictures are worth a thousand words, as well.
