Abstract
A firearm pin assembly is provided. A firearm pin may have a substantially cylindrical member with a lever on one end and a track running along its side. The track may run helically for a portion of its path. The track may also have at least one dimple disposed within its path. The firearm pin assembly may have an aperture for installing a detent and detent spring. The firearm pin assembly may be used in any firearm, including but not limited to a takedown pin and pivot pin assembly in an AR-15 style rifle.
Claims14
A firearm pin device comprising:
- a substantially cylindrical member having a first end and a second end, a pin head, a track and at least one dimple;
- wherein the pin head is attached to the first end of the substantially cylindrical member;
- the track begins proximate the first end of the substantially cylindrical member, runs substantially helically along a perimeter of the substantially cylindrical member for a distance from the first end, and then runs coaxially with the substantially cylindrical member along its perimeter to a point proximate the second end of the substantially cylindrical member;
- and
- the at least one dimple is disposed within the track.
