The sniper rifle was designated ORSIS-Mosin. The upgrade kit has been developed to increase the combat performance of the original firearm. Despite its age, the M1891/30 Mosin sniper rifle remains a popular one owing to a long barrel of high quality chambered for 7.62x54 mm cartridges.

The ORSIS-Mosin sniper rifle has received a new modern metal stock with an adjustable folding buttstock. It has retained the original barrel, bolt assembly, non-detachable magazine and trigger. The updated rifle is fitted with a side mount for various modern sighting systems that increase the accuracy firing range and a plastic handguard in the lower part of the receiver. The ORSIS-Mosin is complemented by a tactical sound suppressor and a bipod. The rifle can be upgraded in the field workshops owing to the modularity of its construction.

It should be noted that the ORSIS-Mosin does not fall short of modern rifles, despite the age of the original firearm. According to the official catalogue by the ORSIS company, the ORSIS-Mosin has a caliber of 7.62 mm, a weight of 5.8 kg, an overall length of 1,264 mm, a length in travel position of 982 mm, a barrel length of 730 mm, a muzzle velocity of 865 m/s, a cartridge capacity of 5 rounds and an accuracy firing range of 1,000 m. The rifle fires 7.62x54 mm cartridges. These specifications match the ones of the latest sniper firearms. For instance, the SV-98 bolt-action sniper rifle (the variant chambered for the 7.62x54 mm cartridges) has a caliber of 7.62 mm, a weight of 6.2 kg, an overall length of 1,270 mm, a length in travel position of 1,270 mm, a barrel length of 650 mm, a muzzle velocity of 830 m/s, a cartridge capacity of 10 rounds and the accuracy firing range of 1,000 m.

Therefore, the ORSIS-Mosin sniper rifle seems to have a promising market outlook. One can allude to the 5-round non-detachable box magazine as an ineffective firearm feeding system; however, a number of sniper rifles developed by the leading small manufacturers - for instance, the M24 SWS (Sniper Weapon System, a 5-round non-detachable box magazine) and the M40A1/A3 (a 5-round non-detachable box magazine) ones by Remington Arms. The ORSIS-Mosin is believed to have improved drastically the well-known precision of the original sniper rifle owing to the integration of modern scopes, the ergonomic stock and the bipod.

The Tula Arms Plant (TOZ, a subsidiary of the High-Precision Weapons holding) offers the civil variant of the M1891/30 Mosin sniper rifle designated KO 91-30. The KO 91-30 has a caliber of 7.62 mm, an accuracy firing range of 2,000 m, a cartridge capacity of 5 rounds, an overall length of 1,230 mm, a barrel length of 730 mm, a weight of 4.5 kg and a cartridge capacity of 5 rounds. The rifle fires 7.62x54 mm cartridges.
