Compact machine OTs-11 "Tiss" for police weapons. Machine was developed in the early 1990s in TsKIB COO Mr.. Tula designers VN. Telesh and YV. Lebedev. Automatic maximally unified with the AKS-74U and developed as its alternative option. The need to create such a sample is explained by the fact, that the AKS-74U armed militia groups capture and detention of the group. They often had to open fire on the premises , because of the high initial velocity sharp-nosed bullet 5.45x39 mm cartridge leading to ricochet and third parties defeat. Also on the open area patterning at a distance 100 m gave such a spread, what about the accurate shooting was not necessary. Therefore, create a new machine for cartridges SP-5 and SP-6, which have a small muzzle velocity trajectory and good ballistics. AT 1993 year TsKIB forces COO Mr.. Tula were made several hundred OC - 11 "Tiss", which were transferred to the Ministry of Interior security forces. Despite the good evaluation by the security forces Tula Arms Plant did not establish serial production machine "Tiss".
When creating a BMP-11 change largely and subjected to barrel muzzle attachment. Receiver with all its contents remain the same. Folding frame butt and pistol grip also inherited from the AKS-74U unchanged. Apply a reduced capacity to store 20 rounds, which makes it possible to reduce the silhouette shooting. Weapons can be equipped with a silencer, while muffling effect of the use of low-speed bullet is much higher.
Automation is operated by the energy of gases bled from the barrel. The barrel is locked by turning the bolt with the production of its two lugs. Fuse - translator fire flag, when you turn it blocks the trigger and handle props reloading, limiting the stroke bolt ago.
