Picatinny In-Line + IMS
Hoyt RX-9 Ultra mount standards
The Hoyt RX-9 Ultra is machined for a Picatinny In-Line sight mount and an Integrate rest dovetail.
Riser mount standards
| Sight mount | Picatinny sight rail (MIL-STD-1913), the Hoyt In-Line family |
|---|---|
| Rest mount | Integrate Mounting System dovetail, plus the 5/16"-24 Berger hole |
| Model year | 2025 |
| Brand | Hoyt |
The 2025 RX-9 Ultra carries the Hoyt In-Line system: a Picatinny rail on the front of the riser for the sight and IMS dovetail slots in the back of the riser for the rest.
For the sight, this riser wants a Picatinny base, so a Mathews Bridge-Lock dovetail bar will not clamp to it without a base swap. For the rest, an Integrate rest clamps to the dovetail and the Berger hole remains for a bolt-on rest.
