The FB MSBS Grot (Polish: Modułowy System Broni Strzeleckiej „Grot”, English: Modular Firearm System "Spearhead") is a family of modular assault rifle developed and manufactured by FB "Łucznik" Radom. Early prototypes were known as the MSBS-5.56 Radon.
There are two basic variants of the MSBS Grot: a conventional configuration assault rifle and a bullpup configuration.[2] The MSBS is the first machine carbine fully designed and produced completely in Poland since World War II as well as the largest firearms sale contract taken on by the Polish arms industry since 1989.[3]

The MSBS-5.56 project was to spawn a total of 11 variants, five in classic configuration (standard rifle, grenade launching rifle, carbine, LMG, DMR) and five bull-pup equivalents, plus MSBS-R, a fixed-stock ceremonial rifle for the Polish Army's Honor Guard Battalion.
