MSBS-5.56 Radon (Modulowy System Broni Strzekeckiej 5,56mm, Radon)

History

MSBS-5. The 56 Radon is fighting for the Polish Army's next standard assault rifle. Development of the weapon began in 2007 and has evolved into a modular system by modern standards, with core components both included in the assault rifle design and forming the basis for the carbine, sniper and squad support weapon forms. Consistent with contemporary offerings seen elsewhere, the MSBS will provide full accessory support in the form of rails for mounting various optics, sights, grips, etc. to allow the infantryman to customize his rifle to the task at hand.

In its current form, the MSBS is seen as a traditional rifle form (magazine feed in front of the pistol grip) and bullpup configuration (magazine feed and action behind the pistol grip). Both forms hold NATO standard 5.56x45mm cartridges and fire from a curved STANAG 30-round magazine.

The modern Polish army depends on the KBS wz. 96, which arrived in 1997 to replace an aging stock of AKM-related assault weapons - all related to the original Kalashnikov AK-47s of the postwar years. A new approach was launched to support the production of all-Polish assault weapons products at the Luznik Arms Factory.

The final design followed a design more closely related to the American AR-15/M16 lineage than previous Kalashnikov guns - the MSBS became a pneumatic, rotating bolt action weapon with a short stroke piston at the heart of its design. The rate of fire is 700 to 750 rounds per minute.

The standard rifle shape weighs 8.2 pounds and is 39 inches long. The unsupported mold weighs 7.5 pounds and has an overall length of 28 inches. The standard model features a foldable shoulder rest for a more compact shape, while the no-back has an inherently short profile but with a larger fixed shoulder rest section. In the bullpup configuration, a full-length barrel is retained, most of its length is wrapped by the body, and the mass of the gun is concentrated at the shoulder.

One of the notable disadvantages of this design is that the shooter's face and hands are very close to the muzzle. Firefighters appreciate the bullpup's accuracy and compactness, and since the late 1970s a variety of bullpup rifles and carbines have been used by many modern militaries - most notably the Austrian Steyr AUG.

Various models are now available under the MSBS name. The basic, conventionally deployed offensive weapon is the MSBS-5. 56K MSBS-5. 56B is a bull configuration model.

Both main forms have five sub-variants covering the base rifle model, another supports 40x46mm grenade launcher weapons, a shortened carbine form and a light machine gun model as well as a Designated Marksman Rifle (DMR) model. Barrel lengths range from 10" to 16".

MSBS-5. The 56R was designed to be a flagship model that primarily launched blanks. MSBS-7. The 62S supports the Soviet 7.62x39mm cartridge and MSBS-7. The 62N supports the 7.62x51mm NATO cartridge, which is required to fulfill the role of a battle rifle.
