Leatherwood/hi-lux mount set - Hi-Lux Optics Malcolm USMC SNIPER Rifle Scope Mounting Kit

I recently purchased this set as a replacement for a Unertl 3/4" scope I have that was missing the front ring. Years ago, I swapped out the front stationary ring to use on a tube sight then sold the item. Yes, I'm an idiot.
These rings are made in China. I can't believe that something like this can't be made in the US. Instead of being like the originals, these are cast steel instead of aluminum. They also use a relatively small contact point on the scope, no where near like the original Unertl's. While I've never seen any wear points on the tube with the original Unertl rings, I believe these will mark the scope over a period of time. Of course, this is my opinion, I'm not going to use them and going to ask for a return. The Unertl scope I have is worth too much to take a chance of damaging it, even though they are outmoded by today's standards.
