The Pecheneg (Pecheneg is an ancient aggressive tribe who lived in what later became Russia; also its name is sometimes transcribed as Petcheneg)
light machine gun was born from experience of Afghanistan and recent
local conflicts, especially the continuous fight with insurgents and
terrorists in Chechnya. Basically, Pecheneg is a standard 7.62x54R PKM
machine gun without the rapid barrel-change option, and intended for
use from an integral bipod as a squad support weapon. It can provide
much more sustained firepower than the standard-issue RPK-74,
and the 7.62x54R cartridge offers a longer effective range (a
rather useful feature in mountainous Chechnya), and, no less important,
better penetration of light structures and improvised covers used by
insurgents in urban and forest environments. Currently Pecheneg
is being issued to certain Russian Army and Internal Affairs
ministry Spetsnaz units operating in Chechnya. The “Pecheneg” LMG can be considered as a modification of the PKM
machine gun, but it is built for only one tactical role; that is, as a
true squad-level light machine gun for mobile infantry and Spetsnaz
troops. Its key difference from the parent design is the barrel, which
is not intended to be replaced in the field (although it can be removed
for inspection and maintenance). The barrel is somewhat heavier than
that of the PKM, and has radial cooling ribs. This is enclosed in a
steel jacket, which runs up to the muzzle to provide forced air cooling
a-la Lewis machine gun of WW1 era. Cooling air enters the jacket
through oval windows at the rear of the jacket, and exits at the
muzzle. Early versions of the Pecheneg had standard PKM-type flash
hider, which resulted in a significant muzzle blast once the gun is
warmed up; current production guns have a special flash hider that
eliminates this problem. At the rear of the jacket there is a carrying
handle permanently attached to it. This handle has a characteristic
elongated profile, as it is also intended to protect the line of sight
from mirages generated by the hot barrel. The manufacturer claims that
the Pecheneg can fire 600 rounds in continuous sustained fire without
any danger to the barrel. Another change from the parent design is
the location of the integral, non-removable folding bipod which is
placed near the muzzle. This feature is said to improve stability and
long-range accuracy when firing from the bipod; but it also limits the
arc of fire available without moving the position of bipod or shooter.
Another consequence of such placement is that the Petcheneg is less
comfortable to fire from the shoulder or the hip, as it does not have a
handguard and the bipod is located too far forward to be used to hold
the gun. However, the Petcheneg has sling swivels and can be fired from
the hip using a sling and carrying handle to hold the gun. In all other respects (action, feed, sights, stock) the Pecheneg is similar to modern PKM machine guns. It also retains the standard PKM
mounting interface and therefore can be used from the same tripod, but
it is always issued as an light machine gun (without tripod mount).
