Very sturdy - Warne 1inch Permanently Attached Ruger 77 High Rifle Scope Rings

Rings were very sturdy. They had zero issues or defects. They were a bit awkward putting on, until I got used to them. This was first time I had used these types. I kept knocking the small locking piece off of the bottom while I was installing....but I got it! Just be patient and try not to rush.
