Mod. 96 Beryl Assault Rifle

The 5.56 mm Mod. 96 Beryl Assault Rifle is an individual selective fire automatic weapon for infantry, airborne and other troops. It is a reliable, accurate, enduring and robustly built rifle, resistant to the environmental challenges.

Sights are open, U-notch type, fitted with integrated tritium-lit night sights, enabling accurate fire both during the day and after dark. For enhanced handling a new, ergonomic pistol grip and optional front grip (fixed to the handguard or detachable using the integrated RIS interface) were fitted.

Beryl has a rifle grenade capability with bullet-trap grenades, enabling live rounds to be used for launching. The stock is rigid, telescoping with optional side-folding stock available. The upper and lower handguard integrated Picatinny rails (MIL-STD-1913 compatible) enable mounting of the different optoelectronic sights.


The MSBS – 5.56 is modular assault rifle system currently under development by the Fabryka Broni „Łucznik” – Radom. It is a state of the weapon platform with unique features.

The MSBS-5.56 is fully designed and manufactured in Poland. The modular firearms system with quick-change barrel is based on a common upper receiver for a conventional (with folding, telescopic stock) or bullpup design.

Thanks to variety of modules the conventional and bullpup design variants can be easily transformed into:

Assault rifle
Assault rifle with underbarrel grenade launcher
Carbine with underbarrel grenade launcher
Designated marksman rifle
Light support weapon

The modular design also allows for adding further configurations in the future. A quick mission-tailored weapon down at the individual end-user level. Highly ergonomic and fully ambidextrous. The MSBS-5.56 assault rifle is fed by a 5.56 mm x 45 NATO intermediate cartridge, but a MSBS-7.62 battle rifle for 7.62 mm x 51 NATO rifle cartridge is also under development.

    I wants it…

    More choice is always better

    I’m noticing a big lack of full auto sear in those pics… does that mean what I think it means???

    • Bean Guy

      Import pls.

      • Twilight sparkle

        That’s what I’m hoping, but that ak is placed next to some random billet ar so I’m thinking neither gun was brought over by Radom

        • Reef Blastbody

          That’s a Canadian made NEA15 carbine.

          • Twilight sparkle

            Thanks, I kept thinking it looked like a gryphon armament logo that was messed up

  • Sledgecrowbar

    I always love these Magpul Masada articles.


    • Twilight sparkle

      It’s not a Masada article it’s about the new magpul pmag


  • Reef Blastbody

    Well, more choices for magazines is always nice. And if they’re built to the same standard as their AK magazines, it should give Magpul some sleepless nights.

    I’m still holding out hope that the MSBS will make it here. And maybe someone can pick up the Beryl, since they got the stench of death cast on them from the rest of IO’s line up, even though IO had zero to do with actually building them. :

    love that my little Broni rollmark…
