Question: What Nut size is the Horizontal Locking Bolt?  Is it Metric or US??
Document: I purchased these based solely on the price. I should have spent a little more on a better quality product. The mounting nut was not the right size and just slips on and off of the screw. Seems like a little attention to detail prior to packaging would have detected this defect. I did not try to get them replaced so I can not rate on their customer service. Probably would not purchase this item again.
You must completly remove the  nut and bolt to remove the mount or mount and scope. A threaded side would have simplified the mounts and a little longer or taller mount would have allowed the nut to align over the picatinny rail instead of through the rail groves. priced well for ecom=nomy installation or more permanet installations.
The fit and finish of these rings are good. I like having 4 locking screws per ring. The flat top surface is a plus when leveling the scope.
I did not see any referance to the dove tail size that this mount fitts. oooooo 22222 2222 3333 4444
I really like the fact that I can use a wrench on the nut that holds these to the base.
The package on these rings say they will fit an outer objective up to 53mm. The item number is RGWM-25M4, they are medium in size. Saddle Height 14mm, Width 21mm, fits 1&#34; tube.
They hold my scope well. I like how there is a thin rubber pad inside the rings to grip the scope. You can tighten the rings to the rail by inserting an allan wrench into a hole on the side of the nut and using it as a lever.
Mounted these rings on the RWS 350 Magnum with a leapers full size TS rated scope. After a few shots the top screws start to loosen up. They don't tighten to a positive grip. Feels a little loose all the time and you tighten some more.. and then you see the screw has bitten into the metal of the clamp. Not as sturdy as I expected them to be.
I like the style and the 4 bolt system on the caps...easy to remove from rifle when not in use
These work as expected, and the side nut is much easier to lock down tight on the rail than are the smaller allen screws common on many rings. They offer plenty of strength on the top ring with four screws. Overall, they are working great and look well made.
Answer: no
