wikipedia said:The 9x39mm cartridge is a subsonic rifle round used in Russian firearms. It was based on the 7.62x39mm M43 cartridge, but with the neck opened up to accommodate a 9 mm bullet. The intent was to create a subsonic cartridge for suppressed firearms of special forces with more power, range and penetration than handgun cartridges, as 5.45x39 mm cartridge introduced in 1974 for AK-74 lacks bullet weight for acceptable energy at subsonic velocities (although there is subsonic load for it). The bullet is heavy, approximately 16 grams, double that of the 7.62x39mm, and is subsonic, avoiding the sound of a sonic boom. The low velocity limits the effective range in comparison with standard non-suppressed assault rifle, but when comparing with handgun rounds commonly fired by SMGs, 9x39 mm round has almost twice the energy of subsonic 9x19 mm round and a bullet with higher BC an sectional density, thus having effective range of about 300 - up to 400 m.
There are 3 versions of the 9x39 mm cartridge: the SP-5, the SP-6, and the PAB-9. The SP-5 was developed by Nikolai Zabelin. It is a conventional lead core FMJ bullet, but developed for accuracy. The SP-6 was developed by Yuri Folov. It has a dense metal core (not covered by jacket at the tip), designed to be armor piercing. It can penetrate 2 mm of steel at 500 meters or 6 mm of steel, 2.8 mm of titanium or 30 layers of Kevlar at 200 meters. At 100 meters it penetrates 8 mm of steel, containing enough power to neutralize the soft target behind. The SP-6 bullet is expensive, so an attempt was made to make a lower cost version, the PAB-9, but it sacrificed too much performance to be usable.
The weapons that use the 9x39mm cartridge include the AS Val, AK-9, OC-11 Tiss and OC-14 Groza assault rifles, the SR-3 Vikhr and 9A-91, and the VSS Vintorez and VSK-94 sniper rifles.

effective range 300-400 m. That don't seem like a Sniper rifle to me, more like an MP5. WHy do they call it a Sniper rifle? Just because of the scope? Don't make sense to me.
They'd call it a sniper rifle because of its application. To classify it as a submachine gun would be very misleading.
Maybe it is a first in a class of its own... perhaps the Urban Marksman Rifle or something like that.

Yea it does seem like the perfect urban sniper rifle, short, light weight for a sniper rifle, and with a hard hitting 9x39mm round. Then theirs the silencer.
right wasn't saying that. just the size of weapon/round 9mm and also wondering how much more powerful if at all it might be compared to an MP5.
The most attractive part to me is the silencer. Although, wonder why it's not recommended to be fired without it. Would it work or is it useless if silencer is off?
With such a short barrel and a silencer on it the range must be pretty low, so I am wondering just why it needs a telescopic sight on it
