Aligning the ARMS 18

[albertacoyotecaller]

Lots of receivers and mounting points are out of spec including lots of the commercial big name firearm makers.

If yours is out of spec, then I doubt any will fit correctly without help from your rotary tools in your toolbox.

you could have a defective mount, not an out of spec Receiver.

Do you have an ARMS 18 mount, or maybe the Pro-Mag clone of it?

It's a real one, not a clone.

Sounds like your mounting grouves may be out of spec. PM me your email and I'll send you some pic's & instructions.
