The Finnish Jalkavaenkivaari m/28 was issued in 1928. Differences between the m/28 and the typical 1891 Russian Mosin-Nagant are:
Shorter And Heavier Barrel
Improved Trigger
Single Piece Extractor/Spring
Shorter Stock
Improved Rear And Front Sights
Forward and Rear Hand Guard Bands Are Held In Place by Screws and Not Springs
M/28 Bayonet is Similar to a Typical Mauser Bayonet in Appearance
Bore Diameter is Typically in the .308 Range.
The m/28 came into its fame when Finnish Sniper Simo Häyhä was credited with over 500 Soviet soldier kills during the Winter War, while carrying the m/28.
