Leupold steel Standard (STD) rings and bases are the most versatile of any mounting system we offer. This specific model fits a Cooper 38/21/57 and is the perfect choice for standard calibers less than .300 Win. Mag. STD rings come in five different heights and are precision engineered to match up with STD 1-piece or 2-piece bases. The front dovetail ring pivots, allowing for lateral adjustment using the rear windage screws while bore sighting. Shims can also be used, reserving the scope's elevation adjustment for BDC (bullet drop compensation) dial applications. Nothing is more crucial than the link between your scope and firearm. That's why our mounts are every bit as rugged and dependable as the Leupold optics they secure. And with a huge variety of mounting systems to pick from, you're sure to find the perfect match for your firearm and style of shooting. Made in the USA and guaranteed to hold up to a lifetime of abuse, Leupold mounts will never let you down.Shipping Notes

It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly.
Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration.
Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.
