The FAST™ Pro Clamp is primarily designed to replace the two-bolt rail clamp on RAXIS™, allowing the end user to mount their light up front next to the laser, which is positioned on top of the rifle. In this use case, the light can fold up into the open pocket directly between the B.E. Meyers® MAWL® and the handguard.

The FAST™ Pro Clamp will also attach to any FAST™ mount using a two-hole clamp, except FAST™ PRO Mount, FAST™ Accessory Riser and FAST™ Thermal Riser. It must replace the FAST™ QD Lever, making it incompatible. This is primarily helpful on shorter handguards, such as a PDW where rail space is at a premium. In such cases, users can also utilize the FAST™ Pro Clamp to mount a KIJI™ illuminator using a SureFire® Pro body.

The FAST™ Pro Clamp is made of 7075-T6 aluminum that is type III hardcoat anodized. It is available only in black and includes a lifetime warranty.
