The mount assembly includes a base that is constructed to be secured to an underlying firearm and an accessory support that is moveable relative to the base. An interface arrangement is provided between the base and the accessory support such that the accessory support can be rotated relative to the base between a first orientation that is laterally inboard of the base and a second orientation that is laterally outboard of the base to accommodate break-action operation of an underlying firearm when the accessory mount assembly is secured to the firearm. ## Claims ### Claim 1 A firearm accessory mount assembly comprising: a base constructed to be secured to an underlying firearm; an accessory support that is pivotably connected to the base; and an interface arrangement between the base and the accessory support that allows the accessory support to be rotated about an axis of rotation between a first orientation that is laterally inboard of the base and a second orientation that is laterally outboard of the base and such that a plane associated with the first orientation and the second orientation is substantially normal to the axis of rotation. ### Claim 2 (depends on 1) The firearm accessory mount assembly of claim 1 further comprising a sight interface formed on a surface of the accessory support that is configured to index an optic relative to the accessory support. ### Claim 3 (depends on 1) The firearm accessory mount assembly of claim 1 wherein the axis of rotation is generally aligned with a longitudinal axis of the base. ### Claim 4 (depends on 1) The firearm accessory mount assembly of claim 1 wherein the base includes a grip guard interface formed on a surface of the base that generally underlies the accessory support when the accessory support is oriented in one of the first orientation and the second orientation, the grip guard interface being configured to index the base relative to a grip guard of an underlying firearm. ### Claim 5 (depends on 1) The firearm accessory mount assembly of claim 1 further comprising a connector configured to cooperate with the base and the accessory support and oriented along the axis of rotation therebetween. ### Claim 6 (depends on 5) The firearm accessory mount assembly of claim 5 further comprising a biasing device associated with the connector and oriented to bias the accessory support into engagement with the base. ### Claim 7 (depends on 1) The firearm accessory mount assembly of claim 1 wherein the interface arrangement is further defined as at least one of a groove and a ridge formed in the base and the other of a groove and a ridge formed in a surface of the accessory support that overlaps the base. ### Claim 8 (depends on 7) The firearm accessory mount assembly of claim 7 wherein the at least one of the groove and the ridge formed in the base and the other of the groove and the ridge formed in the accessory support extend in a longitudinal direction that is aligned with a bore of an underlying firearm when the firearm accessory mount assembly is secured thereto. ### Claim 9 A moveable gun sight mount assembly comprising: a post having a first end constructed to be secured to a firearm; an axis of rotation defined by the post and oriented in a generally vertical direction; and a sight mount attached to the post such that the sight mount is rotatable about the axis of rotation between a first position wherein a portion of the sight mount overlies a barrel of the firearm and a second position in a generally common plane with the first position wherein the portion of the sight mount is laterally outboard of the barrel of the firearm. ### Claim 10 (depends on 9) The moveable gun sight mount assembly of claim 9 further comprising a fastener constructed to cooperate with the post and the sight mount. ### Claim 11 (depends on 10) The movable gun sight mount assembly of claim 10 further comprising a biasing device supported by the fastener and oriented to bias the sight mount into engage with the post. ### Claim 12 (depends on 9) The moveable gun sight mount assembly of claim 9 wherein the portion of the sight mount includes an index arrangement configured to orient an optic relative to the sight mount. ### Claim 13 (depends on 9) The moveable gun sight mount assembly of claim 9 wherein the first end of the post includes an index arrangement configured to orient the post relative to the firearm. ### Claim 14 (depends on 9) The moveable gun sight mount assembly of claim 9 wherein the post has a length that allows the sight mount to be oriented in the first position during use of the firearm and when a stock of the firearm is disposed between the sight mount and the barrel of the firearm when the firearm is collapsed to inoperable position. ### Claim 15 A method of forming a movable firearm accessory mount, the method comprising: providing a base portion constructed to be secured to a firearm; and providing an accessory mount portion that movably cooperates with the base portion such that the accessory mount portion is rotatable relative to the base portion between a first position associated with both use of an accessory during use of the firearm and interfering with unfolding of the firearm and a second position wherein the accessory mount portion is oriented laterally outboard of a cross-section associated with motion of a barrel relative to a receiver during unfolding of the firearm. ### Claim 16 (depends on 15) The method of claim 15 further comprising forming an index engagement interface between the base portion and the accessory mount portion that restrains the accessory mount portion in a respective one of the first position and the second position. ### Claim 17 (depends on 16) The method of claim 16 further comprising biasing the index engagement interface into engagement to selectively restrict rotation of the accessory mount portion relative to the base portion. ### Claim 18 (depends on 15) The method of claim 15 further comprising biasing the base portion and the accessory mount portion into engagement with one another. ### Claim 19 (depends on 15) The method of claim 15 further comprising forming at least one projection on the base portion to index the base portion relative to the firearm. ### Claim 20 (depends on 15) The method of claim 15 further comprising forming at least one projection on the accessory mount portion to index the accessory relative thereto.
