GG&G 30Mm to 1" Ring Reducer

I really like the quick detachments from this company and these pieces allow you to utilize one inch tube optics since the mount itself is designed for 30 mm tube glass.

Thought i would throw this out there. I was looking for a set of reducers for Leopold Mark 4 Rings. These fit perfect. Hope this helps if anyone was looking to reduce there 30mm Steel Mark 4 Rings

I got these to use a 1" tube scope with a set of Weaver 6 screw tactical rings. They are made to the usual GGG quality BUT I found they are only long enough to extend a little over 2 screw lengths of the mount surface. This condition will still work to hold the scope in place but you don't get the full gripping surface and when tightening down all the screws, the front two of each ring might not have the same holding capability or they might loosen prematurely. How this might affect holding zero or other sight alignment durability , I don't know. For range practice or light recoil rifles it probably will be OK. I tightened the 4 rear screws as if it were that type of ring (w/a drop of blue loctite) and then installed the front screws last.One benefit of the reducer not going all the way to the end of the ring is that when positioning the scope for eye relief, my bell ended up slightly inside the front ring (which it would have hit it otherwise), so it all worked out as I don't have to stretch my neck to get a full sight picture.I only dinged the product due to its length (which wasn't mentioned in any data I reviewed) and because they don't mention which way to properly install them (the recoil lip goes in the rear side of the ring). To be fair, these are not made for 6 hole rings but that too is never mentioned.I would like to see at least a small 3rd hole mount spacer included for this type of use. Another way to solve this issue is to mold the pieces with the space tail and then just cut it off if not needed.

Well, they work as advertised, and have had no problems.

Installed easy . Contrary to what one person said, I installed them with the "lip" on the muzzle/front side of the rings to prevent any potential setback during recoil, and so far they haven't slipped and have held zero for around 30 rounds from of a heavy WSM cartridge. I was a little worried that being a plastic material they would crush down over time allowing the screws/tings to work loose, but so far that hasn't been an issue. Time will tell how they hold up, but on this hunting rifle that only gets fired about 20 times a year, they should last a long time, or until change to the proper size rings for the scope.

I bought a used Ruger rifle that came with 30mm diameter, proprietary design, Ruger rings. My scope is 1" (about 24 mm ) so it would not fit. Rather than get new rings, I bought these plastic (or something like plastic) reducers and installed them. The scope zeroed well, and so far, through minimal handling, has worked just fine and held zero at the range. They save the cost of buying, and mounting, new rings for my 1 inch scope. We will see how they hold up when the rifle is used for wild boar hunting this summer where it will get lots of knocking around, but I expect the inserts to do just fine from my current use.

So paired these with a 30mm ccop mount and a nikon prostaff 5. Had intentions of getting a 30mm optic to match the mount but couldn't afford one. The reducers are not wide enough to fill the entire ring so one screw on either side had to be left loose as not touque the mounting surface. They were not perfectly cylindrical but we flexible enough to form to the mount. However the scope has not lost zero even with 1 of 3 screws loose. Would work great with more narrow rings. 3/5 for in initial quality

Polymer reducers that i used on PEPR QD mount. These adapters are not as wide as the PEPR rings, but since they are only flanged on one side, they fit fine. I did not use all the screws on the PEPR mount, just the ones over these reducers. Seems to hold the scope tightly. I wish they were cheaper for what you get.
