Scope rings for airgun or 22 rifle - Barska Rifle Scope Rings

I tried to mount these on a Winchester Wildcat bolt action. The base mounts use a screw driver operated bolt to tighten to base mount. After tightening these they would not hold and the mounts became lose. A friend tried to tighten them back up so I could sight in the gun. This caused one of the mounts to strip it's threads. Optics planet was helpful but could not offer me a refund. They referred me to Barska customer service who never returned my call. I just felt the tolerance for these scope mounts did not have enough adjustment for my gun.
Pros: affordability
Cons: product quality
