This video delves into the less common flapper-locking system in firearms design. It traces the patent by Friberg in 1870 and the practical application in the 1907 Kjellman. The system saw extensive use in the Degtyarev series of machine guns (DP, RPD, DShK) and was also featured in German G41 and G43 rifles. The Mauser company briefly utilized it in their early 1905/06 pistol and 1916 rifle. The description highlights the similarity to later roller-locked systems without detailing them.
