RMR Milling on a shotgun receiver?

[mandreko]

I recently got a cheap Maverick 88, and was pondering if it was possible to mill an RMR (Actually a Holosun, but RMR footprint) onto the back of it, similar to how the Mossberg 940 Pro has, versus installing a picatinny rail and mounting it up higher.

Is this do-able, or a bad idea?

I don't believe that shotgun receivers are thick enough to have that done. Could be wrong.

You might look into the Mesa Tactical rails. If the 500 rail will fit the 88, you should have a nice solution.

Definitely worth looking in to. The flaw I ran into with that setup is the height of the optic. Many people will need to add a cheek riser to the stock. (Was simple enough since I already had a Magpul SGA stock on the gun)

So this setup adds weight of the rail plus the cheek riser. Doable for sure but maybe not ideal

I know shotgun receivers are thin but is there enough room just to mount directly on the receiver ?

I ended up just drilling and tapping the receiver (mostly straight...) and adding a rail for an optic. For me being an amateur and my first time with this, it worked pretty well. One hole wasn't perfectly in line, and it made the screw go in at a bit of an angle, but it's holding tight.
