Important Shipping & Installation Notice: The stock and stock adapter must ship separately from the firearm, directly to your home address. All applicable NFA and 922(r) regulations must be followed before installation.
Please Note: The factory-installed screws are secured with green Loctite threadlocker and require heating to approximately 250°C (482°F) to loosen before removal. Use caution when applying heat to avoid damaging surrounding components.
Magazine compatibility:
All steel AR-15 magazines we tested fit and functioned properly, as did Magpul Gen 2 magazines. Magpul Gen 3 magazines require fitting for compatibility. Some polymer AR-15 magazines have additional external material that can interfere with the magazine well and prevent proper fitment.
(MSBS = Modulowy System Broni Strzeleckiej / Modular Small Arms System)
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.
