The 2023 Phase4 33 shares the V3X 33 geometry and carries the Bridge-Lock sight slot with the Integrate rest dovetail.
For the sight, order a Bridge-Lock dovetail bar; a bracket-mount sight will not use the through-riser slot. For the rest, the Integrate dovetail self-levels an Integrate rest, and the Berger hole is still there for a bolt-on rest.
