The Arisaka Momentary Tailcap is a replacement switch for the Arisaka 300 and 600 Series Light Bodies, plus Surefire Scout lights. Designed to be momentary only with twist for constant on, this tailcap adapter delivers the refined light control preferred by professional weapon instructors and tactical operators.
The momentary-only switch allows you to press for momentary activation or twist for constant on, providing easy and reliable light control. The tailcap can be threaded all the way in for constant on, or backed out approximately two turns to prevent accidental activation during storage or travel. Momentary only switches are the preferred style for many weapon instructors because they simplify light operation.
Constructed from CNC machined 6061-T6 aluminum and finished with a MIL-A-8625 Type III hard coat anodization, the Arisaka Tailcap promises exceptional durability and reliability. The tailcap measures 0.95 inches in diameter, 0.97 inches in length, and weighs 0.4 ounces.
