Return to Models Introduction

In 1927 the Finnish Army adopted the M27 which was an entirely new design built on the Mosin action. It features a 27” heavy barrel and an overall length of 46 ž”. Primary differences are an improved front sight with protective “ears” and a combined front barrel band and nose cap. M27s were built from 1927 to 1940 by Tikkakoski and in 1932 and 1935 at VKT (Valtion Kirvaaritehdas). Tikkakoski barrels are marked with a T in a triangle and VKT barrels are marked with VKT in a polygon. The VKT examples are rare.

Sight Variations
The Finnish M27 rear sight utilizes a Russian M91 base and leaf assembly with modifications. The base has an extra notch cut at the rear for a total of 6 which are numbered 2, 3, 4, 5, 6, and 8, representing hundreds of meters, on both sides of the base. The notch is in a V shape which is a separate piece screwed to the rear of the leaf. The original Russian marks in arshini remain on the rear of the blade. The slide itself has "ears" which project down on each side of the base to help prevent damage to the leaf it is struck from the side.


The front sight base has integral ears to protect the blade and is soldered to the barrel. The blade is dovetailed across the bore axis into a secondary base which is dovetailed the length of the bore into the primary base and held in place with a set screw behind the blade.
