Stupid Question about AA Apocalypse

[Duke Henry]

Looking at the schematics, how does one remove the mounting rail to mount the tank on the gun? Do you have to remove the four screws on the front of the reg, or is there some other way?

Thanks

It has a dovetail mount... which essentially means there is a tracked groove in the top of the reg which the drop slides onto/into. You can then screw down the drop into the reg to secure it.

[Duke Henry]

So, then I imagine there is a set screw or something that screws "down" into the reg, perhaps ahead of the two screws that screw "up" into your drop forward or 45 grip?

Thanks

That's what there is.
