    MSBS Radon modular weapon system is an indigenous development of Polish Military Technical Academy (Wojskowa Akademia Techniczna) and Fabryka Broni „Lucznik” – Radom weapons factory. MSBS stands for “Modułowy Systema Broni Strzeleckiej” – modular small arms system.

    The MSBS-5.56 project was to spawn a total of 11 variants, five in classic configuration (standard rifle, grenade launching rifle, carbine, LMG, DMR) and five bull-pup equivalents, plus MSBS-R, a fixed-stock ceremonial rifle for the Polish Army’s Honor Guard Battalion. As of now, MSBS system consist only of two weapons - MSBS-5.56B Radon-B bullpup assault rifle, intended for Special Forces, and MSBS-5.56K Radon-K standard configuration rifle intended for infantry and other units. Future versions of the MSBS also may include heavy barreled Designated Marksmen rifle and Squad Support Weapon (light machine gun). [​IMG] Although there seems to be little revolutionary stuff in the MSBS (as with most recent assault rifles), it’s the small details that make up the masterpiece. The designers applied for 7 patents and 11 utility models in the process. The backbone of MSBS system is an inverted U-shaped receiver, made from aluminum alloy. This receiver, along with bolt group, return spring, barrel and gas system are common for both current versions of MSBS rifles. MSBS is operated using short stroke gas piston, located above the barrel, and its gas system has manual gas regulator. Breech lock is achieved by a conventional rotary bolt with seven radial lugs that lock into the barrel extension. Ejection windows are made on both sides of the receiver, and weapon can be set up to eject to either side; this requires partial disassembly of the gun and installation of the ejection port cover on the side opposite the “active” ejection window. Non-reciprocating charging handles are located on both sides of the receiver.[​IMG] Polymer stocks are made integral with magazine and trigger unit housings (pistol grips are separate Ar15/M16-compatible parts), and available in two versions – standard (with side-folding, telescoping shoulder stock) and bullpup (with fixed buttplate). Both versions feature ambidextrous safety / fire mode selectors located at the top of the pistol grip, and ambidextrous magazine release buttons located in front of the trigger guard. Bolt stop release buttons are located on the underside of the stock, behind the magazine housing. Both stock versions are interchangeable and attach to receiver using cross-pins. Polymer forends also interchangeable. MSBS rifles are fed from STANAG-compatible (M16-type) magazines. Sighting equipment is installed using Picatinny rail at the top of the receiver. Both MSBS-5.56B Radon-B bullpup and MSBS-5.56K Radon-K standard rifle can mount proprietary knife-bayonet (above the barrel) and specially designed 40mm grenade launcher (below the barrel).

    As an ACR shooter/owner, I have been following the development of the Polish MSBS rifle system with keen interest. It would seem that the platform is getting closer to full deployment (slotted for starting formal force-wide adoption later this year).

    Equipped.PL was given the opportunity to shoot and photo both the traditional and bullpup layouts, fresh off of product improvement efforts. Google translation below;

    Tests MSBS-5, 56B lasted a few months – and introduced several changes to the structure.Simultaneously, a test “classical” MSBS , which also resulted in changes in the weapons – they concerned the details, but quite significant from the point of view of the user:

    • changed the shape of the chamber and the trigger guard;
    • modified-release button the latch assembly with a movable rear position;
    • redesigned inlet magazine slot, formed to make it easier to enter the magazine, as well as to the weapon properly collaborated with magazines of various types, including high-capacity (such as a 60-cartridge magazine Surefire);
    • new wing fuse – removable, so you will replace it with a more corresponding preferences shooter;
    • removable pistol grip – compatible with M4 carbines tricks and their clones;
    • reduced handle overload – does not interfere with the dorsal rail fitted at additional accessories.
    Until MSBS imports rifles in to the US, check out the photos on Equipped.PL Full Google Translated page here.

    Now, Bushmaster… go make a bullpup like this that I can use my current receiver! Oh, and the promised caliber kits while you are at it.
