The Valmet
M82 assault rifle has been designed for for the Finnish airborne troops.
It was also intended to replace weapons with the folding stock. It
was introduced in 1978. The Finnish Army rejected this weapon
because of failures in the design. Nevertheless Valmet produced a
small batch of these assault rifles, mostly in semi-automatic
versions, chambered for a standard NATO 5.56 x 45 (.223 Remington)
round. These rifles were ex mostly to the USA. Production ceased in
1986.
Designers
intended to create a compact weapon. An attempt was made to convert
a well-proven Valmet M76 assault rifle into a bullpup layout. It
allowed to save on overall length of the weapon. Internal design of
this assault rifle is similar to that of the Valmet Rk.76, which in
turn is based on the Soviet
AKM. The
M82 is a gas operated, selective fire weapon. Finnish designers
decided to keep receiver and barrel of it's predecessor. Also this
rifle had a lightened bolt carrier and thinner barrel, to reduce
weight.
The pistol
grip with the trigger was moved to the front of the magazine port.
The safety / fire mode selector switch is far behind the pistol grim
and trigger. It can be set to "safe", "single" or "automatic" fire
modes. A charging handle is located on the right side of the
receiver.
Early
prototypes of this assault rifle featured wooden stocks. Later
models had a polymer housing. It is worth mentioning that the Valmet
M82 was poorly balanced, as most of the weight is in the rear.
The Valmet
M82 has no provision for left-hand ejection. It can only be fired
from the right shoulder. This rifle also lacks a bayonet lug.
Some of the
reasons why the M82 was not accepted to service were it's too hard
noise close to soldier's ear. Also the foresight used to hit the
soldier's teeth during a hard landing with a parachute.
This assault
rifle has fixed dioptric sights, set to the left from the weapon
axis. In such sight the shooter's right eye is focused on the front
sight and the left eye on the rear sight. The two sights overlap at
certain ranges, providing excellent accuracy at fixed range. However
due to the fixed nature the weapons accuracy suffered at variable
ranges. As a result it made shots over 300 meters difficult.
