It was at Tula where Mosin began his career as a weapons designer by first making improvements to the Berdan II and later collaborating with Nagant to design the Rifle of Three Lines of the Year 1891. Some details in Mosin's rifle were borrowed from

that could hold five cartridges to be loaded simultaneously into the magazine. Another detail is the form of the "interrupter", a specially designed part within the receiver, which helps prevent double feeding. The initial rifle proposed by Mosin lacked an interrupter, leading to numerous failures to feed. This detail was introduced in the rifle borrowing from Nagant's rifle. Mosin eventually rose to the rank of Major General and was appointed as the director of the Sestroretsk
