Marking the latest entry into the somewhat brisk resurgence of rifles chambered for the venerable Soviet short .30 caliber, the new Polish MSBS rifle will be chambered in 7.62x39mm, in addition to its already established calibers of 5.56mm and a proposed 7.62x51mm variant. According to the article (and assuming that I’m interpreting Google’s translation correctly), the 7.62x39mm MSBS will utilize existing AK magazines, and a semi-automatic variant will be offered on the civilian market (it did not seem to say whether this meant the American or European civilian market). It also says that about two hundred MSBS rifles have so far been completed – most in 5.56mm.

The full machine-translated text of the article is below:

In Radom Weapons Factory work began on the export variant of rifle ammunition MSBS to 7.62 mm x 39 , fed by magazines interchangeable with magazines from the AK / AKM .

By the end of 2014 in Radom archer is to be completed about two hundred rifles MSBS – 5.56 batch implementation . Some of them will be subject to the qualifying examination ( state ) prior to introduction into the arms Armed Forces ( MSBS – 5.56 instead FAMAS ?, 2014-07-04 ; New FB and new weapons, 2014-07-02 ) .

In addition to weapons -samopowtarzalną , also plans to develop several copies samopowtarzalnych intended for the civilian market . It is not yet certain whether they will appear at shows in the United States , supporting the world’s largest trade fair SHOT Show, which will take place in late January 2015 in Las Vegas.

For several months in the Weapons Factory and they are working on the adaptation of the family arms MSBS to different calibers . Considering the Polish export sales of weapons , an analysis of the requirements of potential users , as well as used their rifle design and supply them ammunition.

In the first place it was decided to create a design based on MSBS to the cartridge 7.62 mm x 39 is supported by the prevalence of rifles AK / AKM and still high popularity of this ammunition among potential export customers . Native weapon is to be powered from a typical 30 -round magazines of rifle AK / AKM .

The same operation Weapon Factory fit into the world standards. Radom designers decided to follow in the footsteps of the Italians, who adapted the model Beretta ARX 160A2 for the Russian supply of ammunition and magazines AK / AKM ( ARX 160A2 in Kazakhstan, 2013-05-14 ; Eurosatory Beretta Russian cartridge , 2012-06-15 ) . Likewise acted Germany , offering a rifle SIG Sauer SIG556R / SIG556ix and introducing Americans to offer Colt CK901 ( Eurosatory 2014 : Colt CK901 for Yemen , 2014-06-19 ) . Czechs also designing your CZ 805 BREN assumed from the beginning that the weapon will be powered cartridge 7.62 mm and 5.56 x 39 mm x 45 and a model of the CZ 807 was sent for tests to India ( Soon in India test McAra , 2014 to 02-16 ) . Today ends the test 7.62 – mm rifle Belgian FN SCAR -H trigger chamber adapted to magazines AK / AKM . Available clones AR -15 firing Russian ammunition , among others, Israeli Gilboa M -43 , produced in small batches for special forces KAC SR – 47 and American Rock River Arms LAR – 47 and MGI MARCK15 – AK47 .

The author speculates that the rifle might appear at SHOT 2015; this would not surprise me, as Łucznik Arms Factory has not been shy about bringing the MSBS along to their SHOT booth in the past.
