- A Weaver or Picatinny rail is utilized for attaching various accessories onto a weapon such as a rifle, shotgun, handgun, or crossbow. These types of rails typically extend in a generally longitudinal direction for aligning an accessory parallel to the weapon bore.
- Typically, the accessory is mounted to the Weaver or Picatinny rail. Mounts known in the art are clamped together and may be clamped onto the rail. Thus, these mounts utilize compressive force to be assembled and/or to be attached to the rail. Unfortunately, these mounts do not provide the accessory in exactly the same orientation each time the accessory is mounted. If the accessory is an optical scope, it is very important that the orientation of the scope, relative to the gun bore, be consistent to avoid having to sight in the gun each time the scope is removed and reattached. Also, known mounts are traditionally made of materials that can scratch and/or dent the accessory when, for example, the accessory is mounted to or when the accessory is removed from the mount.
- Thus, it would be desirable to provide an attachment assembly, a member for attaching and a method for securing the attachment assembly to a weapon that allows the accessory to be consistently and precisely oriented each time the accessory is mounted. Also, it would be desirable to provide an assembly which can mount an accessory to the weapon without denting or scratching the accessory.
- The present invention is directed to a firearm attachment assembly, a member for the firearm attachment assembly, and a method for securing an attachment assembly to a weapon.
- In one embodiment, the firearm attachment assembly comprises an upper mounting portion and a lower mounting portion. Each portion has an inner surface. Also, the firearm attachment assembly comprises a layer affixed to and covering at least a portion of the inner surface of the upper mounting portion and at least a portion of the inner surface of the lower mounting portion.
- In one embodiment, the member for a firearm attachment assembly comprises a portion which tapers from a first end to a middle portion and a threaded portion attached to the middle portion.
- In one embodiment, the method for securing an attachment assembly to a weapon comprises providing an attachment assembly. The attachment assembly comprises a passage formed there through. Also, the method comprises positioning the attachment assembly over a slot in a rail such that the passage is aligned with the slot and inserting a member into the passage and between opposite sides of the slot to secure the attachment assembly to the rail.
