Started with a Yugoslav-marked M72B1 receiver, U R J selectors. Built to RPK length — longer barrel, longer sight radius, Yugo balance.
21.5″ barrel, black-nitride. Generally more accurate than chrome-lined. Muzzle-heavy with the RPK profile, which is what you want for sustained fire.
Fire control: LBE G3. Single-stage, clean break, positive reset.
Yugo receiver and barrel profile kept original; modern parts everywhere aft of the trunnion.
