Question: what size is the ring and the base
Document: I own 3 sets of these. Rugged and reliable. I took them off my muzzleloader and then re-installed, first shot was a ten ring. So they hold true when taken on and off the base. AWESOME product
Previously used see-through scope mounts were so thick at the base that I could not use my iron sights. With these, I can see clearly now. So far, have withstood the recoil of a 45-70 using a stiff hunting reload.
Wanted to be able to use the very low, factory sights. These mount with no interferences at the base so the factory sights can remain in place. They are off-set a bit which allows you to hang the scope out over the top of the rear aperture sight. They appear to grip the polymer rail of the Kel Tec well without movement. Have fired over one hundred rounds and everything is still solid.
This mounting system does exactly what I bought it to do. It mounts my scope while leaving sight line for fixed sights open for closer shots. The system was easy to mount to my Marlin 336, and my scope fits well in the ring mounts. It seems to be of good quality, and comes from a very trusted brand. Overall, I am pleased with the purchase and am unsure what else I can say about the product.
I used these mount to raise-up my Leupold scope so I could also use the iron sights on my Marlin lever action. These rings to a great job of holding the scope steady, and haven't loosened up after 200+ rounds. They leave plenty of room to use the iron sights, which in my case are ghost-ring XS units.The only thing is to read the description and specs carefully. The picture used on these rings shows *ALL* the available options.
quality as I expected from Leupold.a see thru mount is a must in close contact with timber areas...easy to install
i installed these on my ruger 10/22. they installed well and easy. holds scope great and i like the matte finish. great product.
Worked great! No complains. It did what I needed it for. I've gone shooting twice and hasn't come loose or anything
Worked beautifully on my lever action rifle. Scope mounted easy and after shooting a few hundred rounds still no problems. Would buy again.
With the screw running right through the channels, this doesn't get in the way of any irons I've had to use these on. 10/22, AK-47 or 870 Tactical.
Answer: yes
