Great product

Fully adjustable, with good shims. Solid mounts. Star bit which I like because they won't strip easily.

These scope rings are top-notch. They’re solidly built, easy to mount, and hold zero perfectly. The dual compatibility with Picatinny and Weaver rails makes them versatile for multiple setups. The precision machining is impressive, and they securely hold my scope without leaving marks. Highly recommend these for anyone needing a reliable and durable scope mount!

I am using this with a vortex scope. This seems to hold the scope in place nicely. It is nice that this is compatible with a few different tube sizes. I recommend as good inexpensive rings.

Aluminum scope mounts, come with star wrench for adjusting and extra set of bolts. Fabrication is good, all joints are in alignment. Good fit for larger scope tubes. These come with plastic ring inserts to use for a smaller scope tube, manufactured within good tolerances, but questionable whether plastic will hold up for heavier use. Plastic tends to deform under the stress from shooting and incur sliding of scope when shooting. Might not be a good option for smaller scopes.

I have used a number of scope rings over the years. A few were high dollar "L" rings This set is some of the best. For the price you can not go wrong. Put on my gun .223 and mounted a 1" scope. Placed a drop of removable lock-tight to secure. Come with two sets of spacers.Off to the range to sight it in. 5 shots later and scope was on target. I shot a total of 100 rounds. The rings/ scope did not move and was nice an secure.

I recently received up the DISCOVERYOPT Precision Scope Rings and must say, I'm really impressed. The versatility is outstanding, as these rings support three different scope tube diameters - 1 inch, 30mm, and 34mm - all at a very reasonable price. I was able to fit both my 30mm and 34mm diameter scopes without any play, and both held zero perfectly, though I imagine they can't be quite as secure as one-size-only scope rings (but that is not this items intention). The 1.25-inch low height is also a great feature for those who need it: it's especially helpful for rifles with a top rail that's higher than average. It gave me a great view of the eye box. While I didn't need the Weaver compatibility, it's nice to know it’s there for extra flexibility. Overall I would say this is a solid, reliable mount considering it flexibility in accepting various tube-diameters.

I used these for a 1" scope, and I was concerned about using the scope ring adapters since they are made of plastic... however the plastic is firm and the provide a nice firm grip on the scope when torqued properly. The rings themselves feel very sturdy and of high quality. I am glad it uses Torx screws as well which makes it easier to torque it down. For a universal set, this is great, especially for the price.

this is a good set of scope rings the inserts are very good quality and the whole setup is very durable

I used these on a 300 blackout and they held up great. Easy yo use and has the inserts for a different size but I didn’t use those. Well made and easy to attach to my upper.
