Firearm accessory attachment system
A firearm accessory attachment system and method are disclosed. The system has a first body having a longitudinal length, a first protrusion coupled to and extending from the first body in a first direction, and a second protrusion coupled to and extending from the first body in the first direction as the first protrusion, the second protrusion is a first longitudinal distance from the first protrusion. The system also has a second body having a third protrusion coupled thereto, the third protrusion extending in the first direction. The second body is slidable relative to the first body. The system is movable between a locked configuration having a first width and an unlocked configuration having a second width, the second width less than the first width, the first and second widths defined by a direction transverse relative to the longitudinal length.

a second body having a second protrusion coupled thereto, the second protrusion extending from the second body in the first direction adjacent to the first protrusion; and
an actuator configured to lock the system to a firearm or firearm accessory by increasing a width measured across the first and second protrusions along a direction transverse to the first direction.
2. The firearm accessory attachment system of claim 1 , further comprising a third protrusion coupled to and extending from the first body in the first direction, the third protrusion positioned a first longitudinal distance from the first protrusion.
3. The firearm accessory attachment system of claim 2 , further comprising:
a positioning protrusion coupled to and extending in the first direction from at least one of the first or second bodies.
4. The firearm accessory attachment system of claim 3 , wherein:
the first protrusion is a first flanged protrusion with a first proximal surface;
the system has a fourth protrusion, the fourth protrusion being a second flanged protrusion and having a second proximal surface; and
the positioning protrusion is positioned between the first and third protrusions, and has a distal surface.
5. The firearm accessory attachment system of claim 4 , wherein:
the positioning protrusion is coupled to the first body.
6. The firearm accessory attachment system of claim 2 , wherein:
the first protrusion has a first proximal surface; and
the system has a fourth protrusion having a second proximal surface.
7. The firearm accessory attachment system of claim 2 , further comprising:
a fourth protrusion coupled to and extending in the first direction from the second body, the fourth protrusion positioned a second longitudinal distance from the second protrusion, the second longitudinal distance different from the first longitudinal distance.
8. The firearm accessory attachment system of claim 2 , wherein the actuator is actuated by at least one of rotation, camming, or sliding.
9. The firearm accessory attachment system of claim 8 , wherein the actuator comprises:
at least one of a cam lever mounted on the first body, a biasing element, a releasable ratcheting mechanism, a permanent ratcheting mechanism, a cam lobe, or a wedge actuated by a lever or knob.
10. The firearm accessory attachment system of claim 1 , further comprising:
at least one of a travel stop, or a thread disengagement feature, to limit movement of the system to movement between and including a locked configuration and an unlocked configuration.
11. The firearm accessory attachment system of claim 1 , wherein the system is biased towards one of a locked configuration or an unlocked configuration.
12. A method of using a firearm accessory attachment system, the method comprising:
providing a firearm accessory attachment system comprising:
(a) a first body having a longitudinal length, a first protrusion coupled to the first body, the first protrusion extending in a first direction from the first body, and a second body having a second protrusion coupled thereto, the second protrusion extending in the first direction from the second body; and
locking the system to a firearm or firearm accessory by increasing a width measured across the first and second protrusions along a direction transverse to the first direction.
13. The method of claim 12 , further comprising a third protrusion coupled to and extending in the first direction from the first body, the third protrusion positioned a first longitudinal distance from the first protrusion.
14. The method of claim 12 , further comprising:
providing a positioning protrusion coupled to and extending in the first direction from at least one of the first or second bodies, wherein the first protrusion has a first proximal surface;
providing a fourth protrusion having a second proximal surface, wherein
the positioning protrusion is positioned between the first and third protrusions, and the positioning protrusion has a distal surface;
causing the first, third, and positioning protrusions to engage a first side wall of an elongated slot in the firearm; and
causing the second protrusion and the fourth protrusion coupled to the second body to engage a second side wall of the elongated slot, the second side wall opposing the first side wall.
15. The method of claim 14 , further comprising:
causing a first proximal portion of the first protrusion to engage a surface in a first elongated slot in the firearm; and
causing a second proximal portion of the fourth protrusion to engage a third proximal surface in a second elongated slot in the firearm.
16. The method of claim 12 , further comprising:
providing a fourth protrusion coupled to and extending in the first direction from the second body, the fourth protrusion positioned a second longitudinal distance from the second protrusion, the second longitudinal distance different from the first longitudinal distance.
17. The method of claim 12 , wherein the locking comprises:
at least one of rotating, camming, or sliding an actuator.
18. The method of claim 12 , wherein the first, second, and third protrusions are flanged protrusions, the method further comprising:
moving the first and second protrusions into or out of a first elongated slot in the firearm; and
moving the third protrusion into or out of a second elongated slot in the firearm.
19. A method of making a firearm accessory attachment system, comprising:
providing a first body having a longitudinal length, a first protrusion coupled to the first body, the first protrusion extending in a first direction from the first body;
providing a second body having a second protrusion coupled thereto, the second protrusion extending in the first direction from the second body; and
providing an actuator configured to lock the system to a firearm or firearm accessory by increasing a width measured across the first and second protrusions along a direction transverse to the first direction.
