The FB MSBS Grot (Polish: Modułowy System Broni Strzeleckiej „Grot”, English: Modular Firearm System "Spearhead") is a family of modular assault rifle developed and manufactured by FB "Łucznik" Radom. Early prototypes were known as the MSBS-5.56 Radon.

There are two basic variants of the MSBS Grot: a conventional configuration assault rifle and a bullpup configuration.[1] 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.[2]

History

The MSBS program was in development since 2007 by the Military University of Technology (WAT) in Warsaw with cooperation from the firearms manufacturer FB Radom,[3] [4] 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-5.56 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.[5] Additional tests have also shown that MSBS is less susceptible to jamming when using lower quality ammunition or when it is insufficiently maintained,[6] 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.[7]

One of the main design characteristics of the MSBS-5.56 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 MSBS Grot 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 specialised 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-5.56 features fully ambidextrous controls and Picatinny rail, and it may also be fed from standard STANAG magazines.[8]

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.[9] Following the adoption of the MSBS-5.56 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.[9] [10]

During the 2022 Russian invasion of Ukraine 10,000 Grot C16A2 rifles were sent to the Ukrainian military.[11] [12] [13]

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 assault rifles chambered for 7.62×39mm rounds as specified by the customer, along with 40 mm grenade launchers and optical sights DCM-1 Szafir [14] manufactured by PCO S.A.[15]

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.

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.

Currently only the MSBS Grot C in assault rifle, carbine, configuration with a grenade launcher, MSBS Grot R and MSBS Grot S are available. The MSBS Grot B, and the machine gun and designated marksman rifle configurations are not yet produced. Conversion kits between variants are also not yet available. Conversion kit to change the calibre to 7.62×39mm is available.[16]

Both the MSBS Grot C and MSBS Grot B are planned in 5 different configurations and have many common interchangeable parts and can be converted from one to the other:[20] [21]

Polish military adoptionSince 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.[23]

Grot – After the official adoption of the MSBS-5.56 by the Polish Armed Forces, the Grot name was added.

C, B, R, S – variants: classic, bullpup, representative, sport (semi-auto civilian). Denoted after the Grot designation.

10, 16, 20 – barrel lengths, in inches. So far only the 16 in (406 mm) has been adopted by the Polish military.

C, G, M, PS – configurations: carbine, variants with grenade launcher, automatic rifle, designated marksman rifle. Denoted after the barrel length designation.

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).

The M2 was developed to address the issues found on the early production models.[24] [25] The bullpup configuration did not receive the M2 upgrade due to the lack of interest from the Polish military. The changes included a longer upper receiver with M-LOK compatible handguard and heat stop covers, a quick-detach sling mounting points, FB made pistol grip instead of previous Magpul pistol grip due to shortage during mass production, reinforced buttstock, reinforced secondary sights, strengthened, thicker charging handle, reinforced firing pin (not interchangeable with the old one from M1), FB made polymer translucent magazine, new lock (not interchangeable with the old one from M1), and new slide (not interchangeable with the old one from M1).

Grot 762N is a semi-automatic 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.[26]

The Grot 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 Grot 762N, such as the stock, handguard, pistol grip, and trigger are interchangeable between 5.56mm and 7.62mm models.[27]

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

On September 1, 2023, PGZ concluded a contract for the supply of MSBS Grot rifles with an unspecified East-Central African country.[30] On January 31, 2024, the Defense24 portal listed Rwanda as the recipient of Polish-made rifles, but it is not certain whether the deliveries concern Grot or other rifles.[31] In 2024, photos circulated on the web showing a Rwandan soldier with a 7,62x39 Grot fitted with a GP grenade launcher [32]

10,000 Grot C16 FB-M2 assault rifles sent to the Ukrainian Ground Forces during the 2022 Russian invasion of Ukraine.[11] In 2023, it was announced that an unspecified number of Grot C16 A2 rifles had been ordered by Ukraine.[33]

unknown quantity sold to Special Forces Command (USSOCOM).[34]

Test zrealizowano w celu określenia warunków użytkowych broni w przypadku potrzeby prowadzenia ognia o bardzo dużej intensywności. Przebieg prób potwierdził wysokie parametry karabinków MSBS - lepsze niż uznany i ceniony m.in. w środowiskach wojsk specjalnych HK 416. [...] Uzyskanie wyników lepszych od tak popularnej broni jak HK416 sprawia, że można uznać, że MSBS pod względem nagrzewania się nie odbiega od światowej czołówki, a nawet ją przewyższa..
