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.

the system has a fourth protrusion having a proximal surface.
6. The system of claim 1 , 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 third protrusion, the second longitudinal distance different from the first longitudinal distance.
7. The system of claim 1 , further comprising:
an actuator configured to move the system between the locked configuration and the unlocked configuration; wherein
the actuator is actuated by at least one of rotation, camming, or sliding.
8. The system of claim 7 , 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.
9. The 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 the locked configuration and the unlocked configuration.
10. The system of claim 1 , wherein
the system is biased towards one of the locked configuration or the unlocked configuration.
11. The system of claim 1 , further comprising:
an actuator configured to move the system between the locked configuration and the unlocked configuration.
12. A method of using a firearm accessory attachment system, the method comprising:
providing a firearm accessory attachment system, the 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 protrusion coupled to and extending in the first direction from the first body, the second protrusion positioned a first longitudinal distance from the first protrusion, and (b) a second body having a third protrusion coupled thereto, the third protrusion extending in the first direction from the second body; and
moving the system between a locked configuration having a first width and an unlocked configuration having a second width, the second width less than the first width.
13. 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 proximal surface, the fourth protrusion has a proximal surface, the positioning protrusion is positioned between the first and second protrusions, and the positioning protrusion has a distal surface;
causing the first, second, and positioning protrusions to engage a first side wall of an elongated slot in a firearm; and
causing the third protrusion and a 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.
14. The method of claim 13 , further comprising:
causing a proximal portion of the first protrusion to engage a surface in a first elongated slot in a firearm;
causing a proximal portion of the fourth protrusion to engage a proximal surface in a second elongated slot in a firearm.
15. 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 third protrusion, the second longitudinal distance different from the first longitudinal distance.
16. The method of claim 12 , further comprising:
at least one of rotating, camming, or sliding an actuator to move the system between the locked configuration and the unlocked configuration.
17. The method of claim 12 , further comprising:
biasing the system towards one of the locked configuration or the unlocked configuration.
18. The method of claim 12 , further comprising:
manipulating an actuator by hand to move the system between the locked and unlocked configurations.
19. The method of claim 12 , wherein the first, second, third, and fourth protrusions are flanged protrusions, the method further comprising:
moving the first and third flanged protrusions into or out of a first elongated slot in a firearm; and
moving the third flanged protrusion into or out of a second elongated slot in the firearm.
20. A method of making a firearm accessory attachment system, comprising:
