Abstract: A new and improved long gun stabilizer includes a rigid panel element which is connected to a side of the stock of the gun. The rigid panel element projects outward from the side of the stock and is positioned on the side of the stock such that a hand of a user can be placed under the rigid panel element. The rigid panel element rests on the hand of the user, whereby the gun is stabilized on the hand of the user. The rigid panel element includes a contour that is complementary to a contour of a portion of the hand of the user, such as the top portion of the hand. The respective complementary contours provide a snug fit between the top of the hand and the rigid panel element. A channel in the stock receives an edge portion of the rigid panel element. The gun includes a first sight assembly, and the rigid panel element is placed beneath the first sight assembly on the stock.
