The application is further configured to receive a user input indicative of a desired terminal performance value for a projectile and to transmit a signal corresponding to the user input. The digital reticle is further configured to receive the signal corresponding to the user input and to activate the indicator when the predicted terminal performance value does not exceed the desired terminal performance value.

Abstract: A firearm stock with adjustable length of pull and/or comb height is disclosed. In one example, a butt plate assembly includes a tongue defining top and bottom chamfered outside edges. A stock body defines top and bottom chamfered inside edges along a slot opening. Moving a locking assembly to a locked position draws the chamfered outside edges on the tongue against the chamfered inside edges along the slot opening. A locking plate can be used between the fastener and the tongue. In another example, an adjustable comb assembly includes a cheek plate with posts received in post openings that extend into the stock body. A locking lever is coupled to a fastener that extends laterally through the stock body. Moving the lever to the locked position draws together opposite sides of the stock body to constrain the post openings, thereby retaining the position of the comb.
