The ERGO F93 Pro Stock features a fixed cheek piece for a consistent and repeatable cheek weld in some of the eight available stock positions. After the butt is secured in position, the F93 is as rigid as a fixed stock.

Included is an overmolded length buffer tube, a standard jam nut, a rubber buttpad, and a sling plate. At eight receiver to butt plate when fully fell and 12 when fully extended, this stock gives an arrow lots of room for adjustment.
