Need help with picatinny rail for old Ruger 10/22

[Starslinger]

I have a Ruger 10/22 that I think is over 30 years old. It has a thin rail (Weaver? Rimfire?) on top. I'd like to switch out this rail for a modern picatinny rail so that I can mount a Sig Romeo 5 red dot. There are four holes for screws. The second screw hole is one inch from the rear hole, the third hole is 3.5 inches from the rear hole, and the fourth hold is four inches from the rear hole. (Distance between the two rear holes is one inch and the distance between the front holes is half an inch.) Can someone tell me about or link me to a product what will fit on this old 10/22? Thanks for any help!

Nevermind my local gun store has one and says all the screw holes are the same on all 10/22's.

Make sure when you install the new mount that the screw tips do not poke down into the receiver and drag on the bolt.

Whatever you do, do not over tighten the screws, 10-22 receivers are super soft and will strip the holes in a heartbeat. Use a tiny drop of Loctite 242 blue on the screw threads to keep them snug.

Thanks for the tips guys!

Kind of an aside, but I love my tandemkross shadow 2 mount which direct mounts to my vortex venom. It can also accept quite a few other optic footprints too, I had my holosun 507 on there previously

Be careful with cheap stuff from Amazon. I recently switched two of my Rugers over to Kidd scope mounts, the ones I got previously from Amazon were some cheapies and the machining was inconsistent and certain mounts wouldn’t fit. At the very least make sure all your scope mounts and stuff fit before going through the effort of mounting it on your gun.
