• a first mount assembly configured to engage a firearm at a first engagement location on a firearm and a second mount assembly configured to engage the firearm at a second engagement location on the firearm and wherein the firearm includes a bore sight;
• and
• at least one ring assembly configured to detachably couple a sighting device to each the first mount assembly and the second mount assembly prior to the first mount assembly and the second mount assembly directly engaging the firearm so as to align the sighting device with the bore sight wherein the at least one ring assembly includes at least two portions forming a pin that mates with either the first mount assembly or the second mount assembly.

A system for firearm sighting device attachment, the system comprising:

• at least two ring assemblies wherein each assembly includes at least two bifurcated portions forming a portion of an extension;
• at least two mount assemblies wherein each mount assembly includes a receptacle configured to accept the extension and wherein coupling the at least two bifurcated portions expands the extension engaging the mount assembly, and wherein the at least two ring assemblies couple a sighting device to the at least two mount assemblies respectively and wherein the system is configured to couple the sighting device to the at least two mounting assemblies prior to attaching the at least two mounting assemblies to at least one of a plurality of firearms so as to align the sighting device with a bore sight of the firearm.

A system for firearm sighting device attachment, the system comprising:

• at least two ring assemblies wherein each assembly includes an upper portion and a bifurcated lower portion and wherein the bifurcated lower portion of each of the at least two ring assemblies when combined forms an extension;
• at least two mount assemblies wherein each mount assembly includes a receptacle configured to accept the extension and wherein coupling the at least two bifurcated portions to the upper portion expands the extension engaging the mount assembly, and wherein the at least two ring assemblies couple a sighting device to the at least two mount assemblies respectively and wherein the system is configured to couple the sighting device to the at least two mounting assemblies prior to attaching the at least two mounting assemblies to at least one of a plurality of firearms so as to align the sighting device with a bore sight of the firearm.
