What 30mm rings to use on a Marauder

I am not familiar with Marauders but I think you will find something in the Sportsmatch range to suit, I use their mounts on my Anschutz rimfire and my Huntsman, have no complaints with the quality and they are good value for the money, around $50 here in Oz. FX No Limits mounts are another good choice, these mounts have a lot of adjustment for elevation or if you need clearance over the magazine but they are more expensive, Ted has a video explaining how the No Limits mounts work.

The Leapers mounts are good get the highs for clearance. 

Yes I second the Leapers. Good rings for a good price, $18.00. I use the mediums on my Marauder just fine. Low rings would not clear though.

Just bought some from Pyramid Air and mounted them this evening. Try Pyramid part # RGPM-30M4. They worked fine for me, and fairly cheap.

Sportsmatch here. I tried the UTGs, some nameless ones from Amazon. The adjustable Sportsmatch are steady and dont budge for anything.
