Yes. The American Defense Manufacturing AD-RECON-S 40 MOA Scope Mount will work. However, that is a lot of cant on your scope and you may not be able to easily shoot at targets that are closer to you. If you are shooting 1,000 yards out consistently I would say it should be fine. If not, I would recommend a mount with 20MOA.
The American Defense Manufacturing AD-RECON-S 40 MOA Scope Mount is designed to fit scopes with up to a 56mm Objective lens. It is best suited for the AR-10 platform or bolt guns that are in a Chassis system with a full length handguard covering the barrel. I believe it should work for you. You can email us at Techsales@opticsplanet.com and let us know what specific rifle you are using and we can better confirm the compatibility.

Yes, it will. However 40 MOA may be more cant than necessary. A 20 MOA or 0 MOA mount may be more appropriate.
