Magazine for AR15 and Grot and all compatible 5.56x45mm AR-magwell platforms.

  • Durable body made entirely of olive polycarbonate, same color and material as the FB Beryl mags. The transparent housing allows you to verify the amount of ammunition.
  • Textured non-slip exterior surfaces.
  • Capacity markings for 30 and 20 rounds.
  • Notched for use of stripper clips.
  • Made in Poland by FB Radom. The latest model currently used by the Polish Army.
  • Standard capacity of 30 rounds.
  • Polymer components ensure low weight of the magazine - only about 4.25oz.
  • Military pattern follower made of black polymer with double-sided protection against tilting.
  • Low-profile baseplate made of black polymer, secured with a stylized FB logo retaining plate.
  • Compatible with most rifles with an AR magwell chambered in 5.56 and/or .223, made fully compliant to NATO STANAG spec.

FAQ - "When will the Grot come to the US?"
Answer: Both Arms of America and FB Radom are very interested in expanding the MSBS Grot platform stateside, but can provide no additional information or timeframe regarding the import process at this time. We will make an announcement if there is any change. In the meantime, we are able to bring in these mags which are able to be used in a wide variety of existing firearms.
Thank you,

    Perfect for AR-magwell AKs

    Bought these for my M90NP and Galil Ace mainly. They fit great. The M90NP likes to hold tight onto mags, but these flow out well. Of course the Galil has no quirks. A+

    GROT magazine

    These look to be the same quality as the Polish Beryl magazines. I mainly bought them to have Polish made magazines.
