Are krink handguards interchangeable?

looking at picking up a new set of handguards for my krink. The handguards are the russian laminated ones and were originally from a 5.45mm kit. My bulgy krink kit is a 7.62x39. Will these work or fit on my gun??

As long as they are both Bulgarian or Russian they may fit. The Yugoslavian M85 and M92 are completely different.
