Red Dot Mount for 870

Post by wormyjames »

Hey guys,
I have an older 870 SP Turkey gun that is NOT drilled & tapped and I want to add (drill&tap) a mount/rail to the receiver for a red dot sight. This gun has a shallow flat groove on top of the receiver that is just a hair (or a skosh) under 5/16" wide--What rail or weaver mount is made to fit into this groove? I would rather have a picatinny rail or at least something that has a couple slots in it. I ordered a Millet Picatinny rail PC00107 for pretapped guns and it is made to fit a rounded receiver and does not work.
Thanks for your time and help!
Rick

Its been awhile but I think it is Marlin 336 mount that fits that receiver.
Put you plans in the nail scarred hands.

They make a full length mount #429 for an 870, when I drilled and tapped mine, I drilled all the holes and tapped them, then I cut the mount back to just what I needed for the FF sight

Thanks Pullit, I can't tell from the pic if yours is the same as mine--mine has a distinct shallow flat groove on top of the receiver that is the same width as the rib:

I'm sorry for the fuzzy pics--me nad the camera are not getting along well tonight...
I'm wondering if the base you used is machined to fit down in this groove?

The 429 mount is for the 870 and I have mounted more than a few. Yes some of the receivers have a shallow grove and some are like yours.
The mount will work on both.
