As of 2008[update], the CBJ-MS was supposedly in its final phases of development[citation needed] but no production date had been announced.
The gun features a top-mounted Picatinny rail for mounting optics, a progressive trigger for semi- and fully automatic fire, a collapsing wire stock, a grip safety, a threaded barrel, and a hollow foregrip which can be used to hold a spare magazine.
The projectile used by the 6.5×25mm CBJ can be a normal ball bullet, but can also be a 4 mm tungsten kinetic penetrator held inside a non-disintegrating plastic sabot, fired at a high muzzle velocity of 815 m/s (2,670 ft/s) with the ability to defeat most contemporary body armours.
It is also claimed to be effective against light vehicle armors on armoured personnel carriers (APCs).
During trials, the 6.5×25mm CBJ round completely penetrated through the standard CRISAT vest at a range of 230 metres (750 ft).
