The Mathews ARC 30 uses a Bridge-Lock sight mount. Which sight version to order and the trap that catches people out.
Updated 05 September 2026.
What sight fits a Mathews ARC 30 Bridge-Lock slot?
Order a Bridge-Lock dovetail sight. The ARC 30 has the Mathews through-riser slot, so a tested Bridge-Lock dovetail from HHA, Black Gold, CBE, Axcel or Spot Hogg slides straight through it. A standard bracket dovetail does not use the slot.

The Mathews ARC 30 sight mount is Bridge-Lock, which sets what version you order.
The two ends
| Bow sight mount | Mathews Bridge-Lock through-riser dovetail slot |
|---|---|
| Sight version to order | A sight in a Bridge-Lock dovetail version (HHA, Black Gold, CBE, Axcel or Spot Hogg) |
| Wrong-version risk | a mismatched mount bar will not seat in the riser or rail |
| Rest is separate | the rest mount on this bow is the Integrate dovetail, a different question |
The Mathews ARC 30 sight mount is a Bridge-Lock interface, so the fit is set by the mounting bar you order rather than the sight head.
The bar is what sets the fit, not the sight head. Tested 4-inch and 6-inch Bridge-Lock dovetails from those brands pass through the slot; a Montana Black Gold dovetail is the known non-fit.
