The FB Radom MSBS Grot (Polish: Modułowy System Broni Strzeleckiej „Grot”, Template:Lang-en) is a modular assault rifle developed and manufactured by FB "Łucznik" Radom.

There are two basic variants of the rifle: a conventional layout assault rifle and a bullpup.[2] The MSBS is the first machine carbine fully designed and produced completely in Poland since World War II as well as the largest firearms sale contract taken on by the Polish arms industry since 1989.[3]

History

MSBS rifles during the early development stage in 2011

The MSBS rifle was in development since 2007 by the Military University of Technology (WAT) in Warsaw with cooperation from the firearms manufacturer FB Radom,[4][5] and was designed to replace the FB Beryl rifle used by the Polish military since 1997.

During initial tests conducted by the Military University of Technology, the MSBS rifle and its counterpart HK416 were subjected to comparative testing of the barrel and hand-guard for overheating during an intensive firing schedule. According to the tests, MSBS yielded the better results of the two rifles despite having a relatively light and longer barrel profile.[6] Additional tests have also shown that MSBS is less susceptible to jamming when using lower quality ammunition or when it is insufficiently maintained,[7] and had a more manageable recoil when fired in full-auto compared to other assault rifles chambered in the 5.56 cartridge, such as FB Beryl, HK416, FN SCAR-L or CZ BREN 2.[8]

In the summer of 2020, numerous tests of weapons were carried out, and in the publication in January 2021, in a special report prepared by a team of specialists and soldiers under the leadership of a former GROM special unit officer and shooting instructor Paweł Moszner, it was indicated that the Grot C 16 FB-M1 rifle rusts, overheats, stutters with sand the stock breaks on impact, and some defects prevent firing. The report also stated, inter alia, problems with locks that fell apart, hammers that broke off, or fastening belts that detached themselves, and then there was a problem with fastening them.[9][10] The publication of the report sparked controversy both in the military community and in the media.[11][12][13][14][15][16][17][18] All problems and defects are confirmed together with manufacturer FB Radom by military magazines Defence24 [19] and Milmag.[20] They will be removed in Polish Armed Forces by modernizing all the 43 thousand existing M1 rifles to the generation M2 and M3.[21][22][23][24]

One of the main design characteristics of the MSBS rifle is the "modular weapon system". If necessary, a soldier can sacrifice, for example, one standard assault rifle to quickly repair a light machine gun during a firefight. Another feature of the rifle is barrel changeability, as found on the Steyr AUG. This means a soldier may be able to adapt their rifle based on the environment they are in, such as converting a carbine to a designated marksman rifle, in order to engage targets at a greater range. The benefits of this feature allow an infantry squad to have fewer "unique" weapons. MSBS may also be used with components other than the ones manufactured domestically, and it is the first Polish rifle fully compliant with the NATO standards. The MSBS rifle features fully ambidextrous controls and Picatinny rail, and it may also be fed from standard STANAG magazines.[25]

Currently, the rifle is in service with the Polish Territorial Defence Forces and is scheduled to replace FB Beryl as the primary infantry weapon and service rifle of the Polish Armed Forces.[26] Following the adoption of the rifle by the Polish military, the Grot moniker has been added to the MSBS name in honor of the Home Army commander, General Stefan "Grot" Rowecki.[26][27]

During the 2022 Russian invasion of Ukraine 10,000 Grot C16A2 rifles were sent to the Ukrainian military.[1][28][29]

On May 9, 2022, the public was informed about the conclusion of an agreement between the Polish Armaments Group and an undefined East African country for the supply of an unspecified number of MSBS Grot rifles with additional equipment.[30]

Variants

The following variants were designed based on the requests from the Polish Armed Forces to replace currently used firearms such as the AKM, FB Beryl, FB Mini-Beryl, and Pallad grenade launcher.

  • MSBS Grot C (Polish: klasyczny, Template:Lang-en) is the classic variant of the rifle chambered in either 5.56×45mm NATO cartridge with a folding and retractable stock.[31]
    • MSBS-5,56A0 - initial production, 1,000 produced.
    • FB-M1 (MSBS-5,56A1) - first production batch: modified charging handle and additional strap mount point on the picatinny rail.[32]
    • FB-M2 (MSBS-5,56A2) - second production batch: longer handguard to cover the gas block, reinforced firing pin for dry fire practice, improved pistol grip and buttstock.[33]
  • MSBS Grot B (Polish: bezkolbowy, Template:Lang-en) – will be the bullpup variant of the rifle chambered in 5.56×45mm NATO cartridge.
  • MSBS Grot R – is the representative variant of the rifle designed to be used by honour guards which has been adapted to fire blanks and withstand drills. With the modularity of the rifle, the barrel can be swapped to fire live ammunition.
  • Grot S – civilian semi-auto version without bayonet-mount, available with 4 variants of barrels (2022): 10.5, 14.5, and 16 inch in .223 Remington and 16 inch in 7.62×39mm.[34]

The MSBS GROT is a selective fire modular assault rifle which is capable of semi-automatic, 3-round burst and fully automatic fire. It has a cyclic rate of fire of around 700–900 rounds per minute.

Both the Classic and Bullpup variants are planned in 5 different configurations and have many common interchangeable parts and can be in future converted from one to the other.:[35][36]

  • Assault rifle – a standard assault rifle configuration with 16 in (410 mm) barrel.
  • Assault rifle with underbarrel grenade launcher – similar to the assault rifle configuration but with a 40×46mm underbarrel grenade launcher equipped.
  • Carbine – a short barrel variant with a 10 in (250 mm) barrel.
  • Carbine with underbarrel grenade launcher – similar to the carbine configuration but with a 40×46mm underbarrel grenade launcher equipped.
  • Squad automatic weapon – a variant equipped with a heavy profile 16 in (410 mm) barrel.
  • Designated marksman rifle – is equipped with a 16 in (410 mm) barrel and a two stage trigger group.

Currently only conventional layout assault rifle, carbine, representational and semi-auto versions are available. Bullpup layout, grenade launcher, squad automatic weapon and designated marksman rifle are not produced. Modules for conversion between versions also are not available. Conversions kit to caliber 7.62×39mm is available.[37]

Since the Polish ministry of defence ordered 53,000 of the MSBS assault rifles, Fabryka Broni has introduced a military naming designation for the MSBS series.[38]

Grot – After the official adoption of the rifle by the Polish Armed Forces, the Grot name was added.

C, B, R, S – variants: classic, bullpup, representative, sport (semi-auto civilian)

10, 14, 16, 20 – barrel lengths, in inches.

G, M, PS – configurations: assault rifle with grenade launcher, light machine gun, marksman rifle

FB – Fabryka Broni, the manufacturer of this weapon system.

M(x) – number of series (x stands for the generation, for examples, M1 means first generation, M2 is second generation, M3 is planned third generation)

Changes in improved M2 generation:[39][40]

  • longer upper receiver with handguard and heat-shielding covers
  • new sling and new sling mounting points
  • new front grip
  • new main grip
  • reinforced buttstock
  • reinforced iron sights
  • strengthened charging handle
  • reinforced firing pin (not interchangeable with the old one from M1)
  • new bolt (not interchangeable with the old one from M1)
  • new bolt carrier (not interchangeable with the old one from M1)
  • new magazines

Changes announced in M3 generation:[41]

  • new gas block
  • new upper receiver with differently placed cooling holes
  • reinforcement of mechanical sights,
  • a gas regulator adapted to the assembly of a silencer,
  • sealing the lock tensioner guide, preventing sand from getting inside,
  • change the fire selector system to 90 degrees, which is to increase the safety,
  • weight reduction.

The MSBS-7.62N is a semi-automatic sniper rifle/designated marksman rifle chambered in 7.62×51mm NATO cartridge.

The MSBS-7.62N project began in the end of 2015 when Polish Military of Defence announced analytical works for the replacement program of their SVD Dragunov marksman rifle and supplement the bolt-action TRG-22 and Tor sniper rifles currently in service. It was led by the team of Fabryka Broni Łucznik-Radom and Wojskowa Akademia Techniczna (WAT) engineers.[42]

The MSBS-7.62N has two different configurations; one with a 508 mm (20 in) barrel with a fixed adjustable stock and the other with 406 mm (16 in) barrel with the MSBS Grot C's adjustable side-folding stock. Both configurations are part of the MSBS family and some of the parts of the rifle, such as the stock, handguard, pistol grip, and trigger are interchangeable between 5.56m and 7.62m models.[42][43]

The MSBS-7.62N is designed as a semi-automatic rifle but project engineers declared that a fully automatic configuration can be developed if required.[42]

In September, 2019 the MSBS-7.62N was officially announced at MSPO 2019, but since 2022 its production has still not been started.[43]
