A rail mountable device may be provided that is configured to be secured firmly to a rail, such as a rail on a firearm, and released easily from the rail. In one example, the rail mountable device may include a rail clamp that includes first and second rail-engaging surfaces of corresponding first and second ramp members and a cross member that, in response to rotation of a screw, move toward or away from the longitudinal faces of the rail of the firearm to secure or release the rail mountable device to or from the rail. Additional embodiments and related methods are provided.

1. A device configured to mount on a rail associated with a weapon, the device comprising: a housing; anda rail clamp comprising: first and second opposed ramp members,a cross member connected to the second ramp member,a screw adapted to project through the first ramp member and be received by the cross member along a central axis, andwherein the ramp members are adapted to be, in response to a rotation of the screw, simultaneously: pulled toward each other along the central axis, andslid against complementary surfaces of the housing to move the rail clamp toward the rail in a direction substantially perpendicular to the central axis to lock the device with respect to movement in the substantially perpendicular direction. 2. The rail mountable device of claim 1, wherein the rotation causes corresponding rail-engaging surfaces of the ramp members to contact the rail. 3. The rail mountable device of claim 1, wherein the ramp members are adapted to be simultaneously pushed away from each other along the central axis and slid against the complementary surfaces of the housing to move the rail clamp away from the rail in an opposite direction substantially perpendicular to the central axis in response to an opposite rotation of the screw. 4. The rail mountable device of claim 1, wherein the complementary surfaces of the housing are inclined surfaces relative to the central axis and the ramp members comprise substantially inclined surfaces relative to the central axis adapted to slide against the complementary inclined surfaces of the housing in response to the rotation to move the rail clamp in the substantially perpendicular directions. 5. The rail mountable device of claim 1, wherein the cross member is adapted to be received into a groove of the rail in response to the rotation. 6. The rail mountable device of claim 1, wherein the housing comprises first and second rail-engaging surfaces adapted to slide relative to the rail and adapted to contact the rail while the device is mounted to the rail. 7. The rail mountable device of claim 1 further comprising a light source disposed in the housing and adapted to provide light while the device is mounted on the rail. 8. The rail mountable device of claim 7, wherein: the housing comprises a front housing and a main housing;the device further comprises: a circuit board mounted on a front face of the main housing and connected to the light source, andan optical element substantially enclosed by the front housing and adapted to project the light received from the light source; andthe main housing is adapted to dissipate heat associated with the circuit board. 9. The rail mountable device of claim 1, wherein the rail is a Picatinny rail. 10. A method, comprising: providing a device configured to mount on a rail associated with a weapon, the device comprising: a housing, anda rail clamp comprising: first and second opposed ramp members,a cross member connected to the second ramp member, anda screw adapted to project through the first ramp member and be received by the cross member along a central axis; androtating the screw, wherein the ramp members, in response to the rotating, are simultaneously: pulled toward each other along the central axis, andslid against complementary surfaces of the housing to move the rail clamp toward the rail in a direction substantially perpendicular to the central axis to lock the device with respect to movement in the substantially perpendicular direction. 11. The method of claim 10, wherein the rotating causes corresponding rail-engaging surfaces of the ramp members to contact the rail. 12. The method of claim 10, wherein the rotating is performed in a first direction, the method further comprising rotating the screw in a second opposite direction, wherein the ramp members, in response to the rotating in the second opposite direction, are simultaneously pushed away from each other along the central axis and slid against the complementary surfaces of the housing to move the rail clamp away from the rail in an opposite direction substantially perpendicular to the central axis. 13. The method of claim 10, wherein the complementary surfaces of the housing are inclined surfaces relative to the central axis and the ramp members comprise substantially inclined surfaces relative to the central axis adapted to slide against the complementary inclined surfaces of the housing in response to the rotating to move the rail clamp in the substantially perpendicular direction. 14.
