I'd love to put some glass on my old Springfield 87a.

Anyone have one that they have put a scope on?

Best,

Fin

Weaver #12 Top Mount bases.
You'll need to have the receiver drilled and and tapped.

Edited to add: HOLES TOP DEAD CENTER AND IN PERFECT ALIGNMENT! Nothing less is acceptable. Screws well into, but not protruding through the receiver wall.

This is an 2-piece base system, (both base pieces are identical, because the receiver of an 87 is a simple tube with no step or contour differences from front to rear), that will accept almost any Weaver/ Picatinny-style rings with the cross-slot recoil lug. (Not the ones made for the various grooved .22 receivers, though.)

These bases may be available in steel under Weaver's Grand Slam line; otherwise they will be aluminum, (which will work fine and are slightly cheaper than the steel ones, but probably won't match the gun quite as well.)
The Aluminum ones are available in SS-colored or anodized gloss black.
Not sure about the steel ones. Blued, matte blued and SS, probably(?)

Weaver's been around a long time and have about the most comprehensive line of bases available for thousands of different guns but sadly, their quality has dropped recently. (CHINA ). So while the simple bases are foolproof enough that they would be hard to screw up, I would avoid the Weaver brand rings.

Get Warne, Leupold, Burris etc. rings compatible with aforementioned Weaver bases.

Leupold PRW (Semi-permanent "Weaver" ) or QRW (Quick-Release "Weaver") rings are both very nice systems and highly recommended.

Disclaimer-my opinion is based on products purchased a couple or four years ago and may not reflect very current product quality status.

On a round topped receiver you can mark a centerline pretty readily and accurately with a padded vice (or flat table and come clamps) and a square. The important thing is to square up the receiver/barrel assembly using a flat on the bottom side, the recoil lug, etc, so that it is lying on it's side, exactly 90 degrees from the vertical. Then set the square on the table and run it lightly along the top of the receiver with the receiver either taped or coated with a spotting compound. With light pressure as you slide along the recevier, the square will leave a straight line on the exact top center of the receiver where the square contacts the top of the receiver. You still want to use a drill press to make the holes and ensure the bit does not "walk".

Ideally, you can set it up in a milling vice, square it and drill in one operation, but it's still "meaure twice, drill once" as putting metal back after you've removed it is a lot harder than removing it in the first place.

If you lack the tools to do it properly, it's worth taking to a competent gunsmith to have it done correctly.

sounds like I'll just take it to the smith.
