Developed through a decade-long collaboration between FB Radom and Poland’s Military University of Technology, the GROT rifle family represents one of Europe’s most modern small-arms programs. Adopted by the Polish Armed Forces in 2017 and continuously refined through real combat feedback, the GROT evolved into a highly reliable, modular NATO-standard platform. Its proven performance in frontline service—particularly during the Ukraine conflict—has solidified its reputation as Poland’s premier next-generation rifle.
