Shown is a first shot, an early run without texture, of the unnamed new vertical grip from BCM. There will be a picatinny and KeyMod slot version (shown). The grip uses a more comfortable shape for directly grasping when manipulating the firearm, rather than using a cylindrical shape.The grip also has a slightly forward angle to it, which has been preferential to the testers.
The grip locks in by rotating it to lock it in place, after unlocking the mechanism, a couple of turns and it is secured. To really appreciate the ease of attachment you need to see it in action.
