Upfront disclaimer: this is for a shotgun and not ar15.
I bought a berika black op12 and want to add a pic rail adaptor to the keymod fore end. However the distance between the barrel and the fore end is really narrow.
Does keymod screws sit flush with the inside of the fore end or does keymod screw sit proud?
Are there lower profile pic rail keymod adaptor?
Or low profile keymod vertical grip?
