Machine guns, heavy machine guns and auto-cannons are belt-fed. Machine gun belts consist of links (steel made). Depending on the method of connecting the links to each other, there are two types of machine gun belts (firearms belts) - disintegrating and non-desintegrating. We produce both types of firearm belts: *`Machine gun belts 7.62x54mm for Kalashnikov machine guns PK, PKM, PKS are non-desintegrating with 100,200 & 250 links (for rounds) and we produce them. * Machine gun belts belts 7.62x51mm NATO  * Machine gun belts (firearms belts) 5.56x45mm * Belts for 12.7mm heavy machine guns NSV and NSVT (also used as anti-aircraft machine guns) are also within our production program. * Belts 23mm for the most popular anti-aircraft machine gun system (of Russian/Soviet origin) called ZU-23 (ZU-23-2; 2A13). The same 23mm belts are used for the cannons of BMP-23, ZSU-23-4 "Shilka"', ZSU-23-4P SPAAG, Polish ZUR-23, ZUR-23-2S Jod, ZUR-23-2KG Jodek-G, ZU-23-2M Wróbel, ZU-23-2MR Wróbel-II, Bulgarian made BMP-2 and BRM-23.  * Belts 30mm for 2A42 cannon mounted on the vehicles 2TStalker, BMP-2, BMD-2, BMD-3, BTR-90, BTR-T, BMPT, FAHD 280-30, the same 30 mm belts are used by the cannons of the attack helicopters Mil Mi-28, Kamov Ka-50, Kamov Ka-52. The 30mm gun belts are also used in 2A72 cannon mounted on BMP-3. Other uses of 30mm cannon belts: 2K22 Tunguska / 96K6 Pantsir / SA-19/SA-22; The same 30 mm machine gun belts are also used in 2A38 canon. * Belts 30mm for  aircraft gun/cannon GSh-30, mounted on the fighter aircrafts Su-27, Su-30, Su-33, Su-35, Su-34, MIG-27, MIG-29, Yak-141, Sukhoi Su-25 'Fogfoot'.  * Belts 30mm for AGS-17 Plamya (Russian: Пламя) automatic grenade launcher.  We are the only manufacturer of machine gun belts (firearms belts; cartridge belts) in Bulgaria .
