Ergo

The Ergo F93 Pro Stock has a fixed cheek piece for a constant and repeatable cheek weld in any of the eight stock positions. Once the butt is locked, the F93 has the feel of a fixed stock. It is 8" from the receiver to butt plate when collapsed and 12" fully when fully extended. The F93 ProStock weighs just 1.3 lbs. It includes a rubber-like recoil pad, overmolded carbine length buffer tube, standard castle nut, and ambidrextrous sling plate.
