The Unity Tactical FAST Absolute Offset Base (black) attaches to the forward or rearward mounting holes on a Unity FAST LPVO scope mount. Paired with a FAST Offset Optic Adapter Plate (sold separately), it becomes the platform for a mini red dot beside your LPVO.

The Offset Optic Base places the secondary optic at a 35-degree offset from the scope tube for faster transitions from magnified glass to a close-range red dot. When used with the matching adapter plates, the mini red dot sits at a mechanical centerline of 2.05" above the rail—matched to the FAST LPVO height.

Compatibility: requires a Unity FAST LPVO mount and a footprint-specific FAST Offset Optic Adapter Plate (for example RMR/SRO, ACOG-pattern plates, etc.). Construction is 7075-T6 aluminum with Type III hardcoat anodizing in black. Install the base to the LPVO mount holes, then attach the plate and optic with the optic maker’s hardware.

Use case: duty or competition rifles that run an LPVO as primary and need a rock-solid offset MRDS without a separate rail section. Keep plates oriented in forward cantilever, centered, or rearward positions as the plate design allows. Sold by PHLX Tactical.
