Saab Bofors Dynamics CBJ-MS


The Saab Bofors Dynamics CBJ MS is a personal defense weapon/submachine gun designed and manufactured by CBJ Tech AB; it was also manufactured by Saab Bofors Dynamics. It can be chambered for both 6.5×25mm CBJ and 9×19mm Parabellum cartridges.

Development

The CBJ MS was first shown in August 2000. It is an unusual weapon in several respects, not least because it is meant to fulfill the roles of personal defense weapon, assault rifle and, with the addition of a proprietary bipod and 100-round drum magazine, squad automatic weapon.
The gun features a top-mounted Picatinny rail for mounting optics, a progressive trigger for semi-and full 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 CBJ MS is capable of being field-converted to fire one of two types of ammunition. For the purely military role, the weapon fires the proprietary 6.5×25mm CBJ cartridge; but by simply changing the barrel, it can fire 9×19mm Parabellum ammunition for police, training and other operations. The 6.5×25mm CBJ cartridge has the same overall dimensions as the 9×19mm cartridge and generates the same level of firing impulse.
The projectile is a tungsten insert held in a plastic sabot, fired at a high muzzle velocity with the ability to defeat current and future body armours.
It is claimed to be effective against lightly armoured vehicles such as armoured personnel carriers. Advantages claimed for the 6.5×25mm CBJ cartridge include a high impact velocity, a high hit probability due to the flat trajectory, high energy transfer to the target, and low levels of barrel wear and corrosion.
Current cartridge cases are being developed using aluminium. Each 6.5×25mm CBJ cartridge weighs and has an overall length of. The projectile weight is. The combat range of the cartridge is stated to be up to.
