| Geometry | |
| Height, as published Scope height over bore How far the scope's center sits above the barrel's center. It decides your cheek weld and the bullet's path at close range. We calculate only the part above the rail, where makers publish it. | 1.6 in (40.5 mm)Mount Height: 40.5 mm / 1.59 in. Measured: "1.59″ height from rail to optic centerline" |
| Where the height is measured | Ring center above the rail |
| Cantilever Cantilever mount A one-piece mount whose rings sit forward of the rail clamp, usually about 2 in. It moves the scope forward so a thermal's short eye relief works on an AR-15's flat-top rail. | Yes |
| Forward offset Cantilever mount A one-piece mount whose rings sit forward of the rail clamp, usually about 2 in. It moves the scope forward so a thermal's short eye relief works on an AR-15's flat-top rail. | Not published"forward cantilever offset"; no offset figure |
