Atension 2
Inspired by the popularity of the Atension Hinge and the desire for greater diversity in case design, the modular design of the new Atension 2 allows the shooter to choose between the standard two-finger case, or a three- or four-finger release all with the installation of one of two included modular finger pieces.

Other features include Carter�s
Ratchet Adjustment System and built-in clicker for back tension at its finest.
