My 105 clone conversion done by Piece of History on a Saiga SGL31-68. Before I give any details about the parts used on this project. I would like to thank POGI for graciously selling me the proper 105 booster and also a mil. stock and trunnion. The Barrel is a Bulgarian 12.5, Front sight gas block, booster, handguards, retainer, rear sight block, and stock are Russian. Rivets that were replaced are Bulgarian so is the bullet guide.
