The FB MSBS Grot (Modułowy System Broni Strzeleckiej, "Module-based Firearm System.") is a Polish next-generation modular rifle system developed by Fabryka Broni Radom as a replacement for AK-pattern rifles in Polish service. Consisting of a common upper receiver and handguard, the rifle can be configured with different lowers as either a traditional layout (MSBS-5.56K) or bullpup layout (MSBS-5.56B). Modular parts are planned to allow both configurations to be built up as standard rifle, squad support weapon, compact carbine or marksman rifle. 53,000 examples are currently ordered by the Polish military.
Known as Radon during development (the name being first announced in 2010), in 2017 it was announced that the rifle will officially be known as the Grot (a word used for various pointed weapons such as arrows, darts and javelins): this replaces both the old Radon name and seemingly also the MSBS name.
The Polish Ministry of Defense has created a new naming scheme for the Grot rifles, in the following formula:
- Grot - official name of the rifle, followed by a space
- C, B, R - standard, bullpup, or "representative" (inert drill version)
- 10, 16, 20 - barrel length in inches
- G, M, PS - grenadier, machine gun or DMR. This letter is skipped if the weapon is configured as an assault rifle.
- FB - standing for the manufacturer's name
- -Mx - x corresponding to the series number.
For example, a Grot C16GFB-M1 would be a standard layout series 1 rifle with a 16-inch barrel and a grenade launcher.
A grenade launcher module, the GP, is also part of the system, with a standalone version called the GS.
A 7.62mm variant has also entered the prototype phase.
The FB MSBS Grot and variants can be seen in the following films, television series, video games, and anime used by the following actors:
