Red Dot Mount


Hey there,
again I need your support. I want to put a Red Dot on my Mossberg 590 Mariner. Unfortunately the receiver isn't drilled so I am not able to mount a rail.

Is there any mount you guys can recommend to me?
By the way, I saw a lot of 590 Mariners with drilled receivers. Is there any information on which serial numbers they quit to drill the receiver or why they did?

Don't see why it wouldn't.

The main differences in the 500/590 that I am aware of is the barrel is heavier, and has metal trigger guard and such.

Far as I know, the receiver and receiver holes are the same between the two.

Ive had something similar, believe it was made by Millett. Might look into a slip on type cheek riser though, as it will force you to come up off of the stock some for a full field of view through the optic.
