These aluminum Riflescope Rings from Vortex fit riflescopes with a 1" maintube. These rings position the centerline of the scope 1.22" above the top of the mounting rail. They are manufactured from 6061-T6 aluminum and they're compatible with most Weaver-style mounting systems.
I purchased this product because the scope that was gifted to me did not have the correct rings. I found these for a reasonable price. The order came to my home very quickly. I used these new rings for the scope that now sits happily on top of my .22LR. I am, so far, happy with my purchase. Having only just installed these rings I have no idea about longevity. I would recommend B&H to anyone and will be happy to use them again.
These are great scope rings.
