BCM Vertical Grip – Screw Mount
This BCM Vertical Grip attaches to Picatinny rail and is specifically good at just a few things:
1. Mounting to the front of a sub-gun when there isn’t much to grip onto.
2. Chopping down into a shorter grip.
It has an overall length of about 5 inches. By comparison, a normal BCM Vert Grip MOD 3 is 2.5 inches.
Don’t ask them.
