Low rings will typically accommodate a 40mm objective lens, medium rings will fit 44mm objective lens. However, this greatly depends on the rifle you intend to mount your scope to. Email us at Techsales@opticsplanet.com and let us know what specific rifle you have, and that way we can more accurately recommend a set of rings.

To mount the Burris Fullfield II 3-9x40 mm Rifle Scope to an AR15 platform, I would recommend using a dedicated AR15 scope mount. Typically with the AR15 platform, you want to use a high height mount to allow for a more comfortable, natural head and shooting position. I will link a few of my favorite options below that will all work for this scope.

The Fullfield II has enough tube spacing for that spec, however using a one-piece rail will give you more flexibility in mounting solutions. You do not have to stick with a two piece mounting solution on a Savage 110.

This is a non illuminated scope, and will not require a battery.

Although Burris dose have USA made optics this optic was made in china but it tested and inspected in 8th street plant in Greely Colorado.
