Grot – Modułowy System Broni Strzeleckiej
MSBS – 5.56 MM MODULAR FIREARMS SYSTEM Grot
RESEARCH AND DEVELOPMENT PROJECT
The MSBS – 5.56 is modular assault rifle system currently under development by the Fabryka Broni „Łucznik” – Radom. It is a state of the weapon platform with unique features.
The MSBS-5.56 is fully designed and manufactured in Poland. The modular firearms system with quick-change barrel is based on a common upper receiver for a conventional (with folding, telescopic stock) or bullpup design.
Thanks to variety of modules the conventional and bullpup design variants can be easily transformed into:
- Assault rifle
- Assault rifle with underbarrel grenade launcher
- Carbine with underbarrel grenade launcher
- Designated marksman rifle
- Light support weapon
The modular design also allows for adding further configurations in the future. A quick mission-tailored weapon down at the individual end-user level. Highly ergonomic and fully ambidextrous. The MSBS-5.56 assault rifle is fed by a 5.56 mm x 45 NATO intermediate cartridge, but a MSBS-7.62 battle rifle for 7.62 mm x 51 NATO rifle cartridge is also under development.
