Mill 870 Receiver for RMR Footprint?

[I Dont Care About You]

I was looking at the Blackbox Customs website for Glock slides milled for an optic.

Was thinking I'd like to add a small RMR footprint red dot to my 870, in the same way the Mossberg 940 has the top of the receiver inlet for a red dot optic.

Anyone ever hear of this being done? Could it be done? Is there enough meat on top of an 870 receiver to inlet?

Inquiring minds want to know.

the 11-87P was inletted for a shielded adjustable ghost ring rear sight. they have the same profile. Reach out to Tactical Ordnance. they can do it.

OP,
Install a pic rail on the receiver.
Mount the RMR on an American Defense Manufacturing single throw lever mount.

I'd prefer not to go that route because I want to be able to quickly remove the sight and use the front bead on my long vent rib barrel.

This kind of setup is really what I'm after, so that it doesn't interfere with being able to use a regular vent rib barrel and front bead - with the red dot removed.

Tacord is a VanComp dealer are they not? See if Casey can do this, it’s the way I’d want to go. I’d want it on a dedicated barrel and not a receiver.

Thats not a terrible idea at all.

Weirdly VangComp doesn't show that mount on their website. I'll ask TacOrd if it is an option.

They have been doing them for awhile, I’ve seen it a lot on their instagram page. It’s a slick little setup.

I wouldn't think that milling a Rem 870 would be that viable for a RMR footprint but one of the cleanest options would be the Aridus CROM that would still require drill/tap like one might with a picatinny rail.

I think a receiver cut for an Aimpoint ACRO P-2 would make more sense than would a receiver cut for an RMR.

When I was looking for a setup for a 1301 beretta I picked up a scalarworks mount for it and seen they had one for the Rem 870 as well

I've been looking to just have mine drilled for a rail and everyone says the receiver is very thin, to the point that the front screw would actually be shorter than the rear ones. With this in mind I don't see how there could be enough material there to mill for a recessed RMR install.

Link?

Nevermind, I looked it up. Thats not what I'm after because the mount itself would block the front bead when I change back to the long hunting barrel.

Also my 870 is pretty old (ca. 1989) so the receiver isn't drilled.

This is kind of the info I was expecting to hear.
