UNITY FAST OFFSET BASE BLK

When your rifle needs a secondary aiming solution that doesn't interfere with your primary optic, an offset base fills that role. Unity Tactical engineered this mount for shooters who demand redundancy without bulk. Whether you're setting up in Sunnyvale or anywhere else in California, TacticCAL handles your mounting hardware and FFL transfer in Sunnyvale with straightforward service.

Offset Base Design and Application

The FAST offset base positions your secondary optic at 45 degrees to your primary rail system, giving you a backup aiming point without removing your main sight. This configuration keeps both optics accessible and lets you transition quickly if your primary fails. Shooters using this approach often pair it with red dots, magnifiers, or lightweight scopes.

Frequently asked questions

What height does the offset base sit above the rail?

Can I mount this base on any MIL-STD-1913 rail?

Yes—the FAST offset base uses standard picatinny slot geometry, so it works on any MIL-STD-1913 rail system found on AR-platform rifles, handguards, and aftermarket receivers.
