Recently I've read article about new rifle development project called MSBS (Modułowy System Broni Strzeleckiej- Modular Firearms System) 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, which you can see here (click).
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
Total length: 72 cm
Empty weight: 3,3 kg
2007-2010- design and test assault rifle prototypes in bullpup and classic layout
2011-2013- build complete system including assault rifle, sniper rifle, grenade launcher and light machine gun
2014-2016- introduce new weapons
A gun is as simple as it gets in defence R&D we need to shut up and take what we got. The American M16 was jamming all over Vietnam at the height of combat. Army needs to shut up and grow up and ask OFB to make alterations as it inducts.
