The support a bipod gives the front end of a rifle is only half the answer. There’s a trick to shooting well off a bipod. The first is adjusting the height to your position, then trimming the head to reduce cant. Bipods are designed to be “loaded,” or pushed forward so that the robust legs dampen any shake in the gun. You should definitely re-zero your rifle after installing a bipod; some bipods will throw off your zero because they change the geometry of your hold.
