IF YOURS HAS BURRS ON IT LIKE THIS, You Must lap it to remove them or else they could potentially cause harm to your scope tube. I really hope this was just a fluke with this one particular mount. But be Warne-d. Did ya see what I did there?
That sucks. I considered getting this mount. I'm glad I didn't. I used a few of the Warner X-Skel mounts. I have had the ring on those leave marks on a scope tube where the ring segments meet. This was at 15-17 inch pounds. I use kapton tape as a liner with them now.
My experience with Warne mounts is worse than yours. I had a Warne 1.9" MSR mount for a long time. It was excellent. Then I bought 3x more from Warne, and they were terrible. The workmanship and quality were subpar compared with the older one I had. The screws would not go in properly. Even though they had the same exact model #. I returned them.
If its one thing that bugs me is the caps dont close up very close to each other, I got some pri rings for my 16" setup. I have them on a swan sleeve made by pri and I love the setup, I dont like that PRI aluminum and steel ringe are the same dimensions so I can turn a top cap into an MRDS mount. I have to use a separate ring so at some point I will have to change my pri rings our for something else.
I got my first and last Warne MSR mount recently. The flash from the (what looks like) MIM bottom was horrible and made the mount unuseable until flash was removed as it would damage the scope tube considerably. On top of that two screws came cross threaded and damaged from the factory. Try to buy American but the mount I got is horrid. The Aero Precision mounts I have are by far superior in quality for much less money.
Aero mounts bend like a coat hanger... I like aero, but their mounts suck. It's the same problem a lot of the mounts have, for some reason most manufacturers use bubble gum soft 6061.
