When the weapon has been given a separate topic, I will add some other materials from the manual.

Russian School of Design - 1950s.


The base part of the gun is machined from a single piece of steel, all other structural groups are inserted into their respective grooves
and secured by the attachment of another part or by a pin with a wire lock. A 200g hammer and a pry bar are required for disassembly,
only a hammer to assemble. All surfaces are smoothed after machining and edges rounded with a minimum 1mm radius to minimise
the formation of cracks under impact stress. The process in the days before NC milling machines must have been a pretty thick book.


The second piece that I consider a design gem is the cartridge case drainage channel. This unsightly weld of sheet metal ensures that when slow
manual retraction, the school or failed cartridge falls into the set palm, and in the automatic function the cartridges fall at the optimum distance
2-5 m from the gun without endangering the operator.

The 2A7 guns mounted in the AZP-23 Amur kit have a thinner barrel with channels and a water cooling jacket, as well as an electric trigger.
