The bolt in my MAK90 had failed me catastrophically, the ammo had literally crushed my firing pin inside my bolt and bent the retention pins so I couldn't take the bolt apart. I knew that the MAK90 was specific in design and its parts so I bought the assembled bolt. When it arrived I instantly noticed the new bolt was a longer, spring-loaded assembly. My original bolt is shorter and has a free floating pin and I began to worry the new bolt wouldn't fit. I dropped it in my bolt carrier/gas piston and took it out for a test drive. Sure enough she fired beautifully, if not better with the new bolt. The hammer strikes the spring loaded firing pin even cleaner than the original bolt! Very pleased with my purchase!
