FAST™ is a series of mounts and platforms that provide end users with a quicker sight picture than standard height mounts.  A taller optical centerline (mechanical) height provides faster/easier reticle acquisition while wearing electronic ear pro/communication headsets, night vision goggles, gas masks, and plate carriers that can impede a natural shooting position.  It allows for more rapid visual processing of the battlefield by promoting a heads-up posture.

The FAST™ Offset Optic Base attaches to either the forward or rearward mounting holes in the FAST™ LPVO Scope Mount.  Together with a FAST™ Offset Optic Adapter Plate, it provides a base for attaching any number of mini red dot sights directly to the scope mount.  The Offset Optic Base places mini red dot sights at a 35 degree offset from the scope tube for faster transitions.  When used with the Optic Adapter Plates, the mini red dot will have a mechanical centerline of 2.05” above the rail.

The FAST™ Offset Optic Base is only compatible with the FAST™ LPVO Scope Mount and requires a FAST™ Offset Optic Adapter Plate to function.

The FAST™ Offset Optic Base is built from 7075-T6 Aluminum and Type III Hardcoat Anodized Black or FDE*.

    I purchased this mount for my RMR to offset my TA02 on the Cog Mount. If you aren’t running nods this is a great fast set up to get a true 1x optic that’s faster than offset irons . I really like that the offset provides the same 2.05” height over bore as your primary optic whether you’re running a the Unity cog or lpvo mount. If you’re running night vision, I would recommend using a top mounted optic for passive aiming.
