OneLeaf says: Mars mini Adapter & Mounts category: "engineered specifically for the Oneleaf Mars mini". The Mars mini page lists PM-1 through PM-5 and says it "integrates with rifle setups using optional mounts (Picatinny; 30mm ring, 45° offset, etc.)".

| Optic | Who says so | Tube center above the rail (calculated) |
|---|---|---|
| OneLeaf Mars mini 19mmThermal scopes | "For mounting Mars mini thermal sight as a secondary sight on 30 mm magnifying scopes" | Riser: add the unit’s own mount height, which its maker does not publish |
| OneLeaf Mars mini 25mmThermal scopes | "For mounting Mars mini thermal sight as a secondary sight on 30 mm magnifying scopes" | Riser: add the unit’s own mount height, which its maker does not publish |
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.

| Mounts to | |
| 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. | 30 mm scope tube"30 mm scope adapter tube ring" |
| 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. | Not statedClamp type not described; four screws included |

| 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 |
