Does the CBE Engage fit a Mathews Phase4?
Direct fit with the Bridge-Lock version. The Phase4 has the Mathews through-riser slot, and the CBE Engage is offered in a Bridge-Lock dovetail, so it slides straight through with no adapter.

Whether the CBE Engage fits the Phase4 comes down to its Bridge-Lock sight mount.

| Trap | order the Bridge-Lock version, not the standard bracket dovetail |
The Mathews Phase4 sight mount is a Bridge-Lock 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.
