This is the LCSmk1 mount, a collaboration between Lead Faucet Tactical and Cloud Defensive. It is designed to accept the Surefire ST07 Remote Tape Switch for Weapon lights. It features a 3-clamp, Picatinny rail compatible design.
It is machined from 6061-T6 billet aluminum and Mil-Spec Type III hardcoat anodized finish. Additionally, a Mil-Spec Manganese Phosphate finish is applied to the customized and hardened screws. (MIL-STD-171) Proprietary Integrated Cable Channels (ICC) are integrated into both sides of the mount, giving the user the ability to control excess cable and making the mount ambidextrous and reversible. Channels can be used for other cable management as well (IR, etc).
They promise Zero movement. Zero play. Virtually indestructible.
A version compatible with the Streamlight ProTac series series is also available.
