Nice crotch shot.
There should be accessory rails that came with the rail that you can attach to the rail. Put a rail section on the bottom of the handguard tube, and then you attach the grip to the rail.
FYI everyone, RainierArms had BCM lowers in stock tonight for all of about 2 minutes. Yep, I didn't get one. Again. This is ****ing ridiculous. I only need one. RA needs to go from a 2 lower max to a 1 lower per person max.
