Yesterday some new photos and informations about MSBS were unveiled as well as bullpup variant prototypes were presented and fired.
MSBS-5,56B.
Comparrision of MSBS-5,56 and MSBS-5,56B, both ariants have the same 406mm barrel.
New modified upper and lower for MSBS-5,56.
Here are late prototyps of MSBS-5,56 with first two prootypes of MSBS-5,56B, what is interesting tough, is that MSBS-5,56B prototypes are not complete new builds. These were also a test of modularity, and successfull one as well. These two bullpup prototypes use upper receivers and 80% of components from standard variant. This proves that MSBS can be sucessfully and easily reconfigured from standard to bullpup version and vice versa if only components for such conversion are provided.
And this is not an end of the project, it seems our engineers are very ambitious.
The standard and bullpup variants will have each 4 variants:
Standard rifle
Carbine
Magazine fed machine gun
Marksman rifle
However three new weapons based on MSBS concept are in development, first is just presented automatic shotgun:
Second will be representative rifle for representative battalion of Polish Armed Forces.
And finally third will be belt fed machine gun.
It is also said that when basic 5,56x45mm ammunition variant will be finished, more versions of MSBS for different ammunition types will be developed.
Another weapon system that was presented was new military pistol, however no good photos are avaiable yet, because work with patents were not finished yet.
