Optics it fits
DNT Optics says: Fits under DNT's QDS150 and QDM150 mounts, not an optic directly. Recommended uses: HYDRA + QDM150 as a clip-on in front of a 1.93″ LPVO; NVMD + QDS150 behind a red dot at 1.93″; QDS150 + RS43 to raise a digital scope.
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.

| 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. | PicatinnyInterface (rail side): "Picatinny Rail" |
| 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. | NoQuick Detach Mechanism: "N/A" |
| Holds | |
| Holds | Picatinny railInterface (scope side): "Single Picatinny Slot"; designed for the QDS150 and QDM150 |
| 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. | 0.4 in (10.9 mm)Base Height Over Rail: 0.43 in (± 0.05 in). Measured: Measured from top of the rail to the top of the riser |
| Where the height is measured | Measured from a point the maker names (see note) |
| 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. | 2 in (51.3 mm)Horizontal offset 2.02 in (± 0.05 in), "Measured from the center of the bottom positioning block to the center of the top Picatinny slot" |
| Length | 4 in (101.5 mm) |
| Torque | Side plate screw (pan-head Torxplus 25 M5×20×9.25) 30 in-lbs |

Dimensions (L × W × H) 101.5 × 35.0 × 17.3 mm / 4.00 × 1.38 × 0.68 in. With a QDS150 or QDM150 it raises the optic centerline to 1.93 in (± 0.1 in), "Measured with ZULUS V2 and QDS150". Return-to-zero ≤0.1 mil, "Tested to remain zeroed within 0.25 mil after 1,000 impact cycles", recoil rating 800 Gs / .50 BMG.
