The Alpha Flex features a roller-sear double jaw design with an adjustable trigger. The blackened stainless steel jaws are fully radiused, and can be used off the bowstring or with a string loop. The Alpha Flex comes with the standard size wrist strap, brown head and brown stitching. Our patented flex connector is the easiest system on the market today, with just one screw that moves in and out you can fit the release to any hand size. The Alpha is the best double-caliper release in the world.
