Maker says it fits
Interfaces match (calculated)
The optic maker's published mounting interface meets this mount's. That says the parts connect; it does not check eye relief, the length of tube free for the rings, or barrel clearance, and no maker has named the pairing.

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. | Not statedRail type not stated on ATN's page; "move it from platform to platform and still retain zero" |
| 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. | Yes"Adjustable quick detach mechanism" |

| Ring size Ring size The inside diameter of scope rings: 1 in (25.4 mm), 30, 34 or 35 mm. It must equal the scope's tube diameter. Many thermal scopes have a 30 mm tube; others take only their maker's mount. | 30 mm |
| 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 |

| Weight and build | |
| Weight Weight How heavy the device is. Check whether the maker weighed it with or without the battery, because brands do it differently. | Not published |
