20 MOA Rail



Log in to see fewer ads
20 years ago they used to make an MOA rail opposite of what I can find now to shoot high power scopes indoor. Instead of shimming the rear ring or using Burris rings there was a guy that made 15 or 20 MOA rails so you could zero a 25 or 30 power scope indoors at 50 feet. He used to make a lot of cool stuff for the 1022. I got into pistols and can’t find him anymore. Now they make them the opposite way so you can shoot longer distances. Anybody know a place that makes the rails this way?

Why? We have lots of 3 position shooters using 6.5x 20 Leupolds and 6x24 Bushnell or 6x24 Weaver scopes on our Anschutz rifles for 50' indoor league. Never heard of anyone using angled set-up for this. I have a 25moa base with 5x25 vortex that still centers at 50'. Do you have an unusual setup?

Like I said I haven’t shot indoor silhouette in 20 years. Back then you had to shim the rear mount or a different rail. Maybe with today’s scopes they have a lot more adjustment, but no scopes back then you could zero at 50 feet. What about today’s 20 MOA rail. Can you zero it at 50 feet? Thanks for the info

I have several rifles with 20 moa bases, and modern 1" tube scopes and they all zero fine at 50'. 10/22s included. With a 30mm or larger scope tube, you have even more elevation adjustment available. I really don't see a downside to a 20 moa sloped base. If you get a base that extends beyond the front of the receiver a bit, that will allow you to mount your scope far enough forward to use it in sitting or prone position as well. As you've probably noticed, many scopes are mounted too far to the rear, I'm assuming those rifles are only used at the bench. You don't see that scope mounted way to the rear on centerfire hunting rifles as much, probably because the scope drew a little blood on recoil, and the owners fixed it.

I already bought a 20 MOA rail, but I was thinking it was reversed like it used to be. If they have that much adjustment nowadays that would be awesome. You could have the best of both worlds. I used to love to shoot 300 yards with my 1022s. I probably built up two dozen of them. Thanks for the info.

I have had issues with moa tilted rails where the scope did not have enough vertical adjustment to zero at 50 yards. Even at the fullest adjustment they shot high. But I never tried to zero it closer. On paper. , it looks like it would work , even though the clicks are the same, because there is that real close intersection of the line of sight and the bore line.

Just get Burris Signature rings and use the offset inserts opposite of everyone else. You can swap the inserts and re-sight the scope without screwing with the rail.

If you zero your rifle at 50yds, your 17yd impact (zero) will be almost dead on without using any type of rail or shims.

If your scopes center line is 1.5 inches above your bore, your 50yd zero shooting standard velocity ammo will only be about a tenth of an inch low.

I've shot plenty of indoor 50ft indoor 4-p matches, and my Leupold scopes (3-9X and 6.5-20X EFR's) needed just a tiny bit of adjustment from their 50yd zero.

I just figured this out 2 weeks ago. My pistols are sighted in at 50' for indoor bullseye at my local club. Now my partner's brother has a place with a 50 yard shooting range behind his barn. No need to re zero anything. And I can sight in my rifles at the loacal 50' range and be ready for his place. Maybe a click or two at most.
