The adjustable member may include a first surface and a second surface. The first surface of the adjustable member may form at least a portion of the sole of the iron-type golf club head and at least a portion of the rear of iron-type golf club head when the adjustable member is engaged with the iron-type golf club head body in a first orientation. Additionally, the second surface of the adjustable member may form at least a portion of the sole of the iron-type golf club head and at least a portion of the rear of iron-type golf club head when the adjustable member is engaged with the iron-type golf club head body in a second orientation, which is different from the first orientation. ## Claims ### Claim 1 A golf club head comprising: a club head body; and an adjustable member configured to be engaged with the club head body; wherein: the adjustable member is rotatable and reconfigurable between at least a first position and a second position different than the first position, the adjustable member comprising a window; the club head body comprises a fastening protrusion extending from a rear of the club head body, a second protrusion, and a third protrusion; the adjustable member comprises an aperture configured to receive the fastening protrusion, a first recess, and a second recess; the adjustable member is rotatable and reconfigurable without fully disengaging the aperture from the fastening protrusion; when the adjustable member is engaged with the body in a first position, the first recess is configured to receive the second protrusion and the second recess is configured to receive the third protrusion; when the adjustable member is engaged with the body in a second position, the first recess is configured to receive the third protrusion and the second recess is configured to receive the second protrusion; the club head body comprises a first indicator providing a first bounce angle, wherein the first indicator aligns with, and displays through the window when the adjustable member is oriented in the first position, and a second indicator providing a second bounce angle different from the first bounce angle, wherein the second indicator aligns with, and displays through the window when the adjustable member is oriented in the second position; the first indicator is located on the second protrusion of the club head body; and the second indicator is located on the third protrusion of the club head body. ### Claim 2 (depends on 1) The golf club head of claim 1, further comprising: a fastener that engages both the fastening protrusion of the body and the aperture of the adjustable member, wherein the fastener helps secure the adjustable member to the body. ### Claim 3 (depends on 2) The golf club head of claim 2, wherein: the fastening protrusion is hollow and internally threaded; the fastener is a threaded fastener; the adjustable member is immovable when the threaded fastener is fully engaged with the internally threaded fastening protrusion; and the adjustable member is rotatable and reconfigurable between the first position and the second position when the threaded fastener is partially engaged or disengaged with the internally threaded fastening protrusion. ### Claim 4 (depends on 1) The golf club head of claim 1, further comprising: a gasket disposed between the adjustable member and the golf club head body. ### Claim 5 (depends on 4) The golf club head of claim 4, wherein the gasket is configured to extend around an inner perimeter of a front face of the adjusting member. ### Claim 6 (depends on 1) The golf club head of claim 1, wherein the adjustable member is at least partially hollow. ### Claim 7 (depends on 1) The golf club head of claim 1, wherein: the adjustable member further comprises a first indicator and a second indicator on an outside surface of the adjustable member; the second indicator is oriented in an inverted orientation when the first indicator is oriented in an upright orientation; and the first indicator is oriented in an inverted orientation when the second indicator is oriented in an upright orientation. ### Claim 8 (depends on 7) The golf club head of claim 7, wherein: the first indicator provides a first bounce angle; the second indicator provides a second bounce angle; the first indicator is oriented upright when the adjustable member is in the first position; and the second indicator is oriented upright when the adjustable member is in the second position. ### Claim 9 (depends on 1) The golf club head of claim 1, wherein: the first protrusion and the second protrusion prevent the adjustable member from rotating by engaging with the first and second recesses when the adjustable member is oriented in each of the first position and the second position; and the first protrusion and the second protrusion allow rotation and reconfiguration of the adjustable member when the aperture of the adjustable member is only partially engaged with the fastening protrusion of the body. ### Claim 10 A golf club head comprising: a club head body; and an adjustable member configured to be engaged with the club head body; wherein: the adjustable member is rotatable and reconfigurable between at least a first position and a second position different than the first position, the adjustable member comprising a window; the club head body comprises a fastening protrusion extending from a rear of the club head body, a second protrusion, and a third protrusion; the adjustable member comprises an aperture configured to receive the protrusion; the adjustable member is rotatable and reconfigurable without fully disengaging the aperture from the fastening protrusion; the club head body comprises a first indicator providing a first bounce angle, wherein the first indicator aligns with, and displays through the window when the adjustable member is oriented in the first position, and a second indicator providing a second bounce angle different from the first bounce angle, wherein the second indicator aligns with, and displays through the window when the adjustable member is oriented in the second position; the first indicator is located on the second protrusion of the club head body; and the second indicator is located on the third protrusion of the club head body. ### Claim 11 (depends on 10) The golf club head of claim 10, further comprising: a fastener that engages both the fastening protrusion of the body and the aperture of the adjustable member, wherein the fastener helps secure the adjustable member to the body. ### Claim 12 (depends on 11) The golf club head of claim 11, wherein the fastener comprises a mechanism selected from the group consisting of: a threaded fastener, a press-fitting mechanism, and spring loaded locking detents and corresponding recesses. ### Claim 13 (depends on 11) The golf club head of claim 11, wherein: the fastening protrusion is hollow and internally threaded; the fastener is a threaded fastener; the adjustable member is immovable when the threaded fastener is fully engaged with the internally threaded fastening protrusion; and the adjustable member is rotatable and reconfigurable between the first position and the second position when the threaded fastener is partially engaged or disengaged with the internally threaded fastening protrusion. ### Claim 14 (depends on 10) The golf club head of claim 10, further comprising: a gasket disposed between the adjustable member and the golf club head body. ### Claim 15 (depends on 14) The golf club head of claim 14, wherein the gasket is configured to extend around an inner perimeter of a front face of the adjusting member. ### Claim 16 (depends on 10) The golf club head of claim 10, wherein the adjustable member is at least partially hollow. ### Claim 17 (depends on 10) The golf club head of claim 10, wherein: the adjustable member further comprises a first indicator and a second indicator on an outside surface of the adjustable member; the second indicator is oriented in an inverted orientation when the first indicator is oriented in an upright orientation; and the first indicator is oriented in an inverted orientation when the second indicator is oriented in an upright orientation. ### Claim 18 (depends on 17) The golf club head of claim 17, wherein: the first indicator provides a first bounce angle; the second indicator provides a second bounce angle; the first indicator is oriented upright when the adjustable member is in the first position; and the second indicator is oriented upright when the adjustable member is in the second position.
