Low profile folding front and rear firearm sights
Low profile folding front and rear firearm sights are disclosed. The firearm sights can be assemblies including a base, an arm, and a sight attached to the arm. The sight assemblies can also include a spring-loaded pivot pin configured to pivotally couple the arm to the base. The sight assemblies can also include a linking pin connecting the pivot and the arm. The linking pin may be inserted into the pivot pin, such that a longitudinal axis of the linking pin intersects a rotational axis of the pivot pin. The sight assemblies can also include a bushing that includes one or more slots (e.g., locking slots and/or detent slots) and is non-permanently attached to the base. The spring-loaded pivot pin can force the linking pin into the at least one bushing slot when the arm is in a deployed and/or folded (stowed) position.
1. A firearm sight assembly comprising:
a base configured to attach to a firearm rail;
an arm pivotally coupled to the base using a spring-loaded pivot pin;
a sight attached to the arm;
a linking pin connecting the pivot pin and the arm; and
a bushing non-permanently attached to the base, wherein the bushing includes at least one slot;
wherein the spring-loaded pivot pin forces the linking pin into the at least one bushing slot when the arm is in one of a deployed and folded position.
2. The assembly of claim 1 , wherein the at least one bushing slot is one of a locking slot and a detent slot.
3. The assembly of claim 1 , wherein the bushing includes four slots, each separated by approximately ninety degrees, the four slots comprise the following order: a locking slot, a locking slot, a detent slot, a detent slot.
4. The assembly of claim 3 , wherein the bushing can be depressed and rotated to set the desired slot selections for the deployed and folded positions.
5. The assembly of claim 1 , wherein the at least one slot is one of a substantially U-shaped slot and a substantially V-shaped slot.
6. The assembly of claim 1 , wherein the spring-loaded pivot pin can be depressed to remove the linking pin from the at least one bushing slot.
7. The assembly of claim 1 , wherein the sight position can be adjusted relative to the arm.
8. The assembly of claim 1 , wherein the sight includes at least two blades, each blade including an aperture and each blade extending no farther than the arm.
9. The assembly of claim 1 , further comprising a sight screw wheel attached to the sight, wherein the sight position can be adjusted by rotating the sight screw wheel.
10. The assembly of claim 9 , wherein the sight screw wheel is countersunk in the arm.
11. The assembly of claim 1 , further comprising a ball detent located at least partially in the base, the ball detent configured to horizontally align the arm relative to the base.
12. The assembly of claim 1 , further comprising a ball detent located at least partially in the arm, the ball detent configured to apply pressure to the sight.
13. The assembly of claim 1 , wherein a longitudinal axis of the linking pin intersects a rotational axis of the pivot pin.
14. The assembly of claim 1 , wherein the linking pin is integral with the pivot pin.
15. A sight assembly comprising:
a base;
an arm pivotally coupled to the base using a pivot pin, wherein the arm includes a sight;
a linking pin connecting the pivot pin and the arm; and
a bushing non-permanently coupled with the base, wherein the bushing includes a substantially U-shaped locking slot configured to substantially prevent rotation of the linking pin relative to the bushing and a substantially V-shaped detent slot configured to apply some resistance against rotation of the linking pin relative to the bushing.
16. The assembly of claim 15 , wherein the base is configured to attach to a firearm.
17. The assembly of claim 15 , wherein the bushing can be depressed and rotated to set a desired slot selection for when the arm is in one of a deployed and folded position.
18. The assembly of claim 15 , further comprising a spring configured to directly or indirectly force the linking pin into the at least one slot.
19. A firearm sight assembly comprising:
a base configured to attach to a firearm rail;
an arm pivotally coupled to the base using a spring-loaded pivot pin;
a sight attached to the arm using a sight screw, the sight configured to be adjusted by rotating at least one of the sight screw and a wheel rotationally coupled to the sight screw;
a linking pin connecting the pivot pin and the arm; and
a bushing non-permanently attached to the base, wherein the bushing includes at least two slots;
wherein the spring-loaded pivot pin forces the linking pin into one of the at least two bushing slots.
20. The assembly of claim 19 , wherein the at least two slots include at least one of a substantially U-shaped slot configured to substantially prevent rotation of the linking pin relative to the busing and a substantially V-shaped slot configured to apply some resistance against rotation of the linking pin relative to the bushing.
