Frequently Asked Questions

What makes the CBJ-MS trigger system unique?

The CBJ-MS utilizes a progressive trigger. A short pull fires the weapon in semi-automatic mode, while a longer, full pull engages fully automatic fire, eliminating the need for a separate fire selector switch.

How does the CBJ-MS address firearm safety?

Safety on the CBJ-MS is primarily managed by a front grip safety located on the pistol grip. This mechanism must be depressed for the firearm to be discharged, acting as a passive safety feature.

Can the CBJ-MS store extra ammunition?

Yes, the CBJ-MS features an innovative design where a spare magazine can be stored directly within the forward vertical grip, allowing for quicker reloads in tactical situations.

What type of bipod can be attached to the CBJ-MS?

The CBJ-MS is equipped with a muzzle sleeve that is specifically designed to accept a standard M16 "clothespin" style bipod, enhancing stability during firing.
