 Gun springs (springs for pistols, rifles, submachine guns, machine guns, cannons)

Along with ammunition belts & links and rifle magazines we manufacture springs for rifles.

We are licensed for producing gun springs for Russian (Soviet Union) and Israeli systems. We produce all springs for all models Russian submachine-guns and machines guns like Kalashnikov AK, PK, PKM, PKT. In addition to the traditional springs we produce multi-wire springs, magazine springs (springs for gun magazines) and blade-gun springs. Gun springs are produced from wire and strip.

Materials for gun springs: wires and strips from standard materials and  special alloys. Heat treatment and coating of the gun springs: A wide variety of heat treatment and coatings.

Unique technologies and specially designed machines are used for production of some of the gun springs.

The guns contain from dozens to hundreds of springs. Gun springs are essential for right functioning of the guns and they meet very high requirements. These requirements are very specific and require different materials for producing different gun springs. Depending on the particular role, needed gun spring characteristics and available space in the gun, the gun designer uses wire or strip. Most springs for guns require 24-hours setting to solid length, 100% control of all characteristics, passporting etc.  

We produce 95% of the gun springs for the Bulgarian firearms manufacturers. As an internationally-famous springs manufacturer we produce large quantities of gun springs for export.
