Red dot mounts for Mossberg models

This collection contains red dot mounts for Mossberg pistols and shotguns. Both mounts are Outer Impact type C. They fit red dots with the Trijicon RMR, C-More RTS or Docter footprint.

• MC1 and MC2 pistols: one mount for the MC1c, MC1sc, MC2c and MC2sc. It replaces the rear sight. It does not fit the Optics Ready variants. See Red dot mounts for Mossberg MC1c.
• Shotguns: one mount for the Mossberg 500, 535, 590, 835, 930 and 935. See Red dot mounts for Mossberg 500.

Outer Impact makes the mounts from aluminium in the USA. No permanent modifications are needed.

Frequently asked questions

Can I put a red dot on my Mossberg without an optic cut?

Yes. The mount goes into the rear sight dovetail in place of the rear sight. No milling and no permanent changes, so you can put the rear sight back at any time.

Can I install the mount at home?

Yes, if you have a sight pusher or a punch.

1. Drift the rear sight out of the dovetail.
2. Push the mount into the dovetail and tighten it.
3. Screw the red dot onto the mount with a drop of threadlocker on each screw.

You find the tools in Installation tools.

Which red dots will fit?

It depends on the mount you choose. Every mount takes one footprint or a group of footprints. For Mossberg we have mounts for the Trijicon RMR, Docter and C-More RTS footprints.

Find the footprint of your red dot in its specifications and take the mount that names it.

Does the 500 mount fit my 590?

Yes. The mount fits the 500, 535, 590, 835, 930 and 935.

Does the MC1 mount fit my MC2?

Yes. It fits the MC1c, MC1sc, MC2c and MC2sc, but not the Optics Ready variants.
