The bracket is similar to bracket the factory 74 on the modernized sniper rifle, but has a non-adjustable spherical heel.

When tested rifles large number of shots (up to 6000) delays and breakdowns were not the weapon. Survivability barrel rifles exhausted, locking assemblies satisfactory strength.

Cool information. D.N. Bolotin's Soviet Small Arms and Ammunition shows this model and labels it "Experimental semiautomatic sniper carbine SKS-45". Does the Russian site indicate anything other than prototypes?

Google translate has a lot of trouble with Russian  One mis-translation I could confirm: fuse = safety

No. 536 = Tula

Looks very much like these examples I've seen on the .ru boards (and subsequently seen on carbinesforcollectors.com & others):





The moderator who posted these at http://www.yaplakal.com/forum2/st/50/topic1326167.html / http://ruforum.mt5.com/threads/84272-voennaya-tema/page84had this to say:

Sniper SCS Photos of Bulgarian arsenal. At the end of the 50s (closer to 60 m) in Bulgaria, a limited number of experimental specimens sniper SKS was manufactured. In my view, the information that is available at this time for sniper SKS, very curious !

Very similar to the Yugo sniper concept with the receiver mounted, PU inspired mount.

One might wonder why they went to such trouble with this carbine when they had other rifles/carbines more suitable. I would like to own one of these for the historical significance.
