The Cobalt Kinetics Ambi safety is produced to the highest (and most stringent) of standards. They are designed to accommodate Right hand, Left, and Ambi shooters alike. A crisp, 45 degree throw allows the end user to quickly engage (and dis-engage) the safety as needed. These are manufactured for our line of rifles, but are now available for the aspiring personal builder. Run our products with pride, experience the Cobalt difference!
