Optics it fits
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.)".
Maker says it fits
| Optic | Who says so | Tube center above the rail (calculated) |
|---|---|---|
| OneLeaf Mars mini 19mmThermal scopes | Mars mini package includes "PM-1 Picatinny Rail Adapter x 1" | OneLeaf does not publish the height of the unit’s optical axis above its mounting base |
| OneLeaf Mars mini 25mmThermal scopes | Mars mini package includes "PM-1 Picatinny Rail Adapter x 1" | OneLeaf does not publish the height of the unit’s optical axis above its mounting base |
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.

| 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 |
