Does the HHA Nytrx fit a Hoyt RX-9 Ultra?
Needs a Picatinny base. The RX-9 Ultra mounts the sight on a Hoyt In-Line Picatinny rail, so the HHA Nytrx dovetail bar will not clamp to it. Add a Picatinny base or use the HHA Nytrx in a Picatinny mount if one is offered.
Bow sight mount
Picatinny sight rail (MIL-STD-1913), the Hoyt In-Line family
Sight
HHA Nytrx, a Bridge-Lock-capable dovetail sight
Whether the HHA Nytrx fits the RX-9 Ultra comes down to its Picatinny In-Line sight mount.
The two ends
| Bow sight mount | Picatinny sight rail (MIL-STD-1913), the Hoyt In-Line family |
|---|---|
| Sight | HHA Nytrx, a Bridge-Lock-capable dovetail sight |
| What to order | A Picatinny base for the HHA Nytrx, or a Picatinny-mount version |
| Trap | a Bridge-Lock dovetail bar is a different interface from a Picatinny rail |
The Hoyt RX-9 Ultra sight mount is a Picatinny In-Line interface, so whether the HHA Nytrx fits depends on the mounting bar, not the sight head.
The HHA Nytrx is a dovetail sight offered in a Bridge-Lock version, which is why it drops into a Mathews slot but needs a base change for a Picatinny rail and cannot use a Center Mass slot.
