Does the CBE Engage fit a Prime RVX 4?
Needs a Picatinny base. The RVX 4 mounts the sight on a Hoyt In-Line Picatinny rail, so the CBE Engage dovetail bar will not clamp to it. Add a Picatinny base or use the CBE Engage in a Picatinny mount if one is offered.

Sight
CBE Engage, a Bridge-Lock-capable dovetail sight
Whether the CBE Engage fits the RVX 4 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 | CBE Engage, a Bridge-Lock-capable dovetail sight |
| What to order | A Picatinny base for the CBE Engage, or a Picatinny-mount version |
| Trap | a Bridge-Lock dovetail bar is a different interface from a Picatinny rail |
The Prime RVX 4 sight mount is a Picatinny In-Line interface, so whether the CBE Engage fits depends on the mounting bar, not the sight head.
The CBE Engage 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.
