The Hoyt RX-8 uses a Picatinny In-Line sight mount. Whether the Rocky Mountain Horizon fits, what version to order, and the trap.
Updated 05 September 2026.
Does the Rocky Mountain Horizon fit a Hoyt RX-8?
Needs a Picatinny base. The RX-8 mounts the sight on a Hoyt In-Line Picatinny rail, so the Rocky Mountain Horizon dovetail bar will not clamp to it. Add a Picatinny base or use the Rocky Mountain Horizon in a Picatinny mount if one is offered.
Bow sight mount
Picatinny sight rail (MIL-STD-1913), the Hoyt In-Line family
Sight
Rocky Mountain Horizon, a Bridge-Lock-capable dovetail sight
Whether the Rocky Mountain Horizon fits the RX-8 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 | Rocky Mountain Horizon, a Bridge-Lock-capable dovetail sight |
| What to order | A Picatinny base for the Rocky Mountain Horizon, or a Picatinny-mount version |
| Trap | a Bridge-Lock dovetail bar is a different interface from a Picatinny rail |
The Hoyt RX-8 sight mount is a Picatinny In-Line interface, so whether the Rocky Mountain Horizon fits depends on the mounting bar, not the sight head.
The Rocky Mountain Horizon 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.
