A foldable firearm sight assembly including a leaf spring is disclosed. The disclosed assembly may include a base, a sight arm, and a leaf spring. The base of the sight assembly may be configured to attach to a firearm rail using, for example, a clamp bracket and a clamp bolt. The sight arm may be rotationally coupled to the base, and the leaf spring may be positioned between the base and the sight arm. When installed in the sight assembly, the leaf spring may be deflected and may apply a biasing force to the sight arm, causing the sight arm to favor either a deployed or stowed (undeployed) position. The sight arm may be lockable in stowed and/or deployed positions using a tooth and aperture configuration. In such lockable cases, the arm may be unlocked/released by manually depressing an end of leaf spring.

A firearm sight assembly comprising: a base configured to attach to a firearm rail;a sight arm rotationally coupled to the base; anda leaf spring positioned between the base and the sight arm;wherein the leaf spring provides a biasing force to the sight arm in a direction substantially away from the base; andwherein the leaf spring defines an aperture and the sight arm includes at least one tooth configured to insert into the leaf spring aperture to lock the sight arm in a stowed and/or deployed position. 2. The assembly of claim 1, wherein the leaf spring acts as a detent to resist the rotation of the sight arm. 3. The assembly of claim 1, wherein the sight arm includes trunnions configured to nest in pockets on sides of the base. 4. The assembly of claim 1, wherein the base includes hubs configured to nest in pockets in the sides of the sight arm. 5. The assembly of claim 1, wherein the leaf spring extends beyond at least one end of the sight arm to allow an end of the leaf spring to be manually depressed to unlock the sight arm when locked in the stowed and/or deployed position. 6. The assembly of claim 1, wherein the leaf spring includes tabs on an end of the leaf spring, the tabs configured to be placed in and provide force against pockets in the base. 7. The assembly of claim 1, wherein a portion of the base acts as a fulcrum for the leaf spring. 8. The assembly of claim 1, wherein the maximum overall height of the assembly is less than 5 cm when in the deployed position. 9. The assembly of claim 1, wherein the overall length of the assembly is less than 120% of the overall height of the sight arm. 10. The assembly of claim 1, wherein the sight arm includes a removable sight post. 11. The assembly of claim 1, wherein the sight arm and/or the base include rotational stops to resist rotation of the sight arm relative to the base in at least one direction once the sight arm is in the deployed position. 12. A foldable firearm sight assembly comprising: a base configured to attach to a firearm rail;a clamp bracket configured to fix the base to the firearm rail;a clamp bolt connecting the clamp bracket to the base;a sight arm rotationally coupled to the base at a pivot point; anda leaf spring positioned between the base and the sight arm;wherein the clamp bolt acts as a fulcrum for the leaf spring; andwherein one of the sight arm and the leaf spring includes at least one of an aperture, hole, bore, notch, slit, and groove and the other of the sight arm and the leaf spring includes at least one of a tooth, post, and protrusion configured to engage with the at least one of an aperture, hole, bore, notch, slit, and groove to lock the sight arm in a stowed and/or deployed position. 13. The assembly of claim 12, wherein the aperture is defined in one of the sight arm and the leaf spring and the tooth is on the other of the sight arm and the leaf spring, the tooth configured to insert into the aperture when the sight arm is in a stowed and/or deployed position. 14. The assembly of claim 12, wherein the leaf spring provides a biasing force to the sight arm. 15. The assembly of claim 12, wherein the leaf spring extends beyond at least one end of the sight arm to allow an end of the leaf spring to be manually depressed to unlock the sight arm when locked in the stowed and/or deployed position. 16. A method of unlocking a firearm sight assembly, the firearm sight assembly including a base, a sight arm rotationally coupled to the base, and a leaf spring positioned between the base and the sight arm, wherein the sight arm and leaf spring are configured to lock the sight arm in a stowed and/or deployed position, the method comprising: depressing an end of the leaf spring to clear the sight arm from the leaf spring;pivoting the sight arm to a new position; andreleasing the end of the leaf spring. 17. The method of claim 16, wherein the end of the leaf spring extends beyond at least one end of the sight arm. 18. The method of claim 16, wherein the end of the leaf spring extends beyond at least one end of the base. 19. The method of claim 16, wherein at least one aperture is defined in one of the sight arm and the leaf spring and a tooth is on the other of the sight arm and the leaf spring, and wherein the tooth is configured to insert into the at least one aperture when the sight arm is in a stowed and/or deployed position. 20. The method of claim 16, wherein the base is configured to attach to a firearm rail. 21. The method of claim 16, wherein the base is integral with at least one of a firearm and a component removably attached to the firearm.
