Tube center above the rail is calculated only when the mount maker says where its height is measured from and the optic maker states a tube diameter; each blank says which figure is missing.

| Clamps onto Picatinny and Weaver rails The slotted rails most mounts clamp onto. Picatinny (MIL-STD-1913) has evenly spaced slots of one width; Weaver slots are narrower and spaced irregularly. Weaver mounts fit Picatinny; the reverse not always. | Picatinny"attach the base to a 20mm rail" (OneLeaf's own LQD spec tables list "Picatinny Rails 20 mm") |
| Quick-detach QD mount A quick-detach mount: a lever or throw clamp takes the scope off the rail without tools. Worth it only if it goes back to the same zero, so mark the rail slot. | No"No Allen wrench is needed; simply twist the rail clamp screw nut by hand" (hand nut, not a lever) |

| 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. | Not published |
| 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. | Not stated |
| 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 |
