MSBS-5.56

MSBS-5,56 (short for Modułowy System Broni Strzeleckiej kalibru 5,56 mm or English: Modular Firearm System 5.56mm Calibre) is an assault rifle currently under development as a future service rifle of the Polish Army. There are two basic variants currently being developed, based on a common upper receiver: a bullpup version and a standard version with folding, retractable stock.

Thanks to a variety of modules, both variants can be easily transformed into a carbine, sniper rifle or squad light machine gun. Additionally, plans exist to develop a 12-gauge combat shotgun based on the platform, as well as rifles in common Soviet calibers for export.
