I've read article about new rifle development project called MSBS (Modułowy System Broni Strzeleckiej- Modular Firearms System) 5,56 mm and it seems to be quite interesting as first modern non AK-based assault rifle designed in Poland.
Prototype is gas operated with short-stroke piston and rotating bolt. Weapon uses standard M-16 family magazines. All switches, charging handle, and shell ejector are ambidextrous. There are two variants under development- bullpup and classic layout. Rifle is designed to be used with GPBO-40 grenade launcher.
1 gen:
Classic layout variant:
Top: older prototype with M4 buttstock and right-side only shell ejector
Bottom: current version
Total length: 98 cm
Empty weight: 3,7 kg
Bullpup variant:
Total length: 72 cm
Empty weight: 3,3 kg
It looks like a M4, Sig 556, and that new beretta had an inbred child:)
