The Abyss Flex is an all-brass, three finger, Comfort Flex, thumb activated release, that uses the same exact handle dimensions as the Fulkrum Flex. The Abyss Flex also uses the same Lever Alignment System (LAS) Technology as the Fulkrum Flex meaning if you want a hinge/back-tension release you can pick up the Fulkrum Flex and be comfortable shooting the new style in no time. Crisp, clean and comfortable shots are what you can expect with the Abyss Flex.
