Thanks everyone! It seems most optics rated for centerfire pistols or rifles would be acceptable so that’s good to know.
Nothing so needs reforming as other people's habits - Mark Twain
Tact is the knack of making a point without making an enemy / Where is the wisdom we have lost in knowledge?
I've bought three 870 Police trade-ins over the last few months. The price was RIGHT on all three. Two of them have 18.5" bead sight barrels. I plan to get the receivers drilled and tapped on the top of both of these guns. Then I will be ordering the ACRO mounts from Vang Comp.
I have two ACRO P1s sitting around doing nothing since upgrading the dots on my handguns. A 12 gauge seems like a really good host for the ACRO or any Aimpoint for that matter.
