Arisaka Tailcap Features The Arisaka Defense Tailcap is CNC machined from 6061-T651 aluminum and finished with a Type III hard coat anodized coating for long term durability in the field. Designed as a momentary only switch it gives the shooter intuitive control without the risk of accidentally bumping the light to constant on during stressful manipulation. Twisting the cap allows the user to lock the light into constant on when needed while threading it fully in restores the default momentary function. Made in the USA the tailcap is built to the same standard as the light bodies it is designed to service. This tailcap is compatible with the Arisaka 300 and 600 series light bodies the 18350 and 18650 series bodies and Streamlight ProTac as well as Surefire Scout and E series lights making it a versatile replacement switch across several platforms. Backing the cap out approximately two turns from fully threaded helps prevent unintended activation while the light is stored or carried a useful safeguard for duty and range use. At roughly 0.3 ounces and under an inch long it adds negligible bulk to any light setup. For owners replacing a worn or damaged switch this tailcap restores smooth dependable operation.
