About
What it is, and why it matters
The Grot 762N is a semi-automatic designated marksman rifle chambered in 7.62x51mm NATO, developed by Fabryka Broni Lucznik-Radom in Poland as a DMR variant of the MSBS Grot modular assault rifle platform. The MSBS-7.62N project began in late 2015, and the rifle was first exhibited during Polish Army DMR trials in 2021. In early 2023, the Polish Army signed a contract for the initial purchase of 250 rifles under the official designation Grot 762N. The rifle is available in two configurations: a 508mm (20-inch) barrel variant with a fixed adjustable stock for dedicated marksman use, and a 406mm (16-inch) barrel variant with the MSBS Grot C's adjustable side-folding stock for more mobile operations. The 20-inch version weighs approximately 5 kg without accessories. The Grot 762N shares many interchangeable components with the standard 5.56mm MSBS Grot carbine family, simplifying logistics and training. The short-stroke gas piston operating system with a rotating bolt ensures reliable cycling, while the free-floating barrel and precision trigger contribute to the accuracy required for designated marksman engagements.
Poland's MSBS Grot program represents one of the most ambitious indigenous small arms development efforts in NATO's newer member states. The Grot 762N extends this program from a standard assault rifle into the precision marksman space, giving Poland a domestically produced capability that reduces reliance on imported Western or legacy Soviet-era weapon systems.
The Grot 762N represents Poland's effort to develop a complete family of indigenous small arms based on the MSBS (Modularny System Broni Strzeleckiej - Modular Firearms System) platform. The 5.56mm MSBS Grot was adopted as the Polish Army's standard assault rifle in 2017, and the 7.62mm DMR variant extends the platform's reach. The rifle accepts standard SR-25 pattern 7.62 NATO magazines. The initial 2023 contract for 250 rifles is expected to be followed by additional orders as the Polish Army expands its DMR capability across infantry formations.
