The M27rv is based on the M27 rifle in service with the Finnish Army in an attempt to standardize calibers and weapons for cavalry units with the rest of the army.  It borrows some features from the German Kar98a which it replaced.  This example is owned by JMKDEVCO who was kind enough to take the pictures and allow them to be used here.   Total production numbers were less than 3,000 units and the attrition rate during the Winter and Continuation Wars was relatively high since the M27rv was issued to elite cavalry units who saw extensive combat.  This makes for a rare and desirable addition to any Mosin Nagant collection.  For more information on the production and use of the M27rv see Vic Thomas' article "The Finnish M27" at Mosin-Nagant Dot Net.

The overall length of the M27rv is approximately 44" and the barrel length is approximately 24".  This is about 3" less than the standard M27 infantry rifle.  This example was built at Tikkakoski, as were most M27rv, on a 1915 Tula receiver.  The re-use of captured and purchased receivers was standard procedure during Finnish Mosin Nagant production and no Finnish receivers were made.

One of the features borrowed from the Kar98a is the bent bolt handle and the shallow recess in the stock for clearance.  This is the only model of Mosin Nagant other than snipers which has a bent handle.  The bottom of the knob is flattened and checkered for a more sure grip.  The trigger is a standard M27 type which is unique to the M27 in general.

Another M27 feature shared by this M27rv is the winged bolt connector which is numbered to match the bolt and fits in the corresponding slots added to the receiver.

The sights are typical of M27s with the protective ears projecting downward along each side of the base from the slide.  The 200 meter notch was cut by the Finns on a used Russian rear sight base.  The notches were then re-numbered for meters rather than the Russian arshins.  The nose cap is an early type without the reinforcing tabs along each side.

The buttstock has the typical Mosin Nagant slot filled and the rotating swivel on the bottom as is usual for M27s.  In addition, it has a vertical slot cut through the butt which is another feature borrowed from the Kar98a.

The rear barrel band is unique to the M27rv with a fixed bar welded to the left side.   It is held in place with a screw through the stock from the right side.

The stock has the typical Finnish splice which was developed at the beginning of standard M27 production.  The stock disk is the for the 4th Uusimaa Calvary Regiment, rifle #37.

The handguard is another unique feature of the M27rv with the long rear section between the rear sight base and the rear barrel band.  This one has an interesting arsenal repair.
