THORNTAIL KeyMod™ .830" Offset Adaptive Light Mount is designed to directly attach a handheld flashlight with a body measuring .830" of an inch (.825"to .832") to a KeyMod Compatible Forend, eliminating the need for separate bulky 1913 rail sections and a separate light mount. IWC designed our new THORNTAIL .830" Offset Adaptive Light Mount with AMBI mounting capability, so you can place the tail cap of the weaponlight light in up to 6 separate mounting positions on a forend with 3 KeyMod attaching locations. Rugged, durable design, each component CNC machined from a single piece of 6061-T6 Billet Aluminum. THORNTAIL can also be cantilevered past the front of the forend (based on forend design). Designed and manufactured in COLORADO by Americans working at IMPACT WEAPONS COMPONENTS for HALEY STRATEGIC PARTNERS.
