  • Notched for use of stripper clips.
  • Made in Poland by FB Radom. The latest model currently used by the Polish Army.

  • 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,

    Only 4 stars because I haven't shot with them yet look great not bulky and seem to load and eject from rifle very smooth moving follower/ anti tilt strong spring as good as a pmag and not as bulky.

    You're buying it for the look, and that's okay

    These mags work at least as well as Lancers, which is to say I've had a few issues with them. I've had a few failures to pick up rounds in my AR when suppressed (it's a Colt, so it's not out-of-spec), but they've worked flawlessly in my VHS-2, Sig 556xi, and some of my friends' guns. Translucent polymer is finicky, so that's to be expected somewhat.

    Really though, at the pricepoint, when gen 2 PMags are like $10, the reason to buy these is because they look cool in your gun, which they certainly do. Buy a handful to have around and add a splash of green to your rifle at the range from time to time.

    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.
