These are a fixed-length chassis block meaning that all different inlets are cut from the same length of billet. For this reason, forend length will vary based on the inlet. The length will range from 10-12" with the long actions having the shortest forend legth (because of the longer receivers). With that said, the distance from the grip to the front of the chassis remains the same across the board so your stance really does not change when you are on the rifle offhand.
