Firearm insert

Abstract

A single multifunction part that is removably insertable into multiple firearm housings having different trigger configurations, such that the sear mechanism is housed in the insert and the trigger mechanism is not mounted, guided or housed in the insert. The multifunction part, the insert, can thus be used in multiple firearm housings and in various configurations to reduce firearm manufacturing costs across different product lines.

What is claimed is: 
     
         1 . A multifunction part for a firearm for housing a selected firing control assembly and to operably interact with a selected trigger assembly, the multifunction part being configured to be installed on a variety of different firearm configurations by virtue of lacking an integral trigger mechanism 
     
     
         2 . The multifunction part of  claim 1  comprising guide rails for a slide or bolt. 
     
     
         3 . The multifunction part of  claim 1 , wherein the multifunction part is configured to operably accept a straight pull trigger mechanism. 
     
     
         4 . The multifunction part of  claim 1 , wherein the multifunction part is configured to operably accept a rotational trigger mechanism. 
     
     
         5 . The multifunction part of  claim 1 , wherein the multifunction part is configured to operably accept a guide wire trigger mechanism. 
     
     
         6 . The multifunction part of  claim 1 , wherein the multifunction part is composed of any material suitable for use in a firearm. 
     
     
         7 . The multifunction part of  claim 1 , wherein the selected trigger assembly is selected from one or more different types of trigger assemblies. 
     
     
         8 . An improved modular part for a firearm, the part functioning as a housing for a firing control mechanism to interact with a selected trigger assembly, the improvement consisting of the absence of an integrated trigger assembly. 
     
     
         9 . The improved modular part of  claim 8 , further comprising guide surfaces for a bolt or a slide to reciprocate. 
     
     
         10 . The improved modular part of  claim 8 , further comprising guide rails for a slide or a belt. 
     
     
         11 . The improved modular part of  claim 8 , wherein the selected trigger assembly comprises a straight pull trigger. 
     
     
         12 . The improved modular part of  claim 8 , wherein the selected trigger assembly comprises a rotational trigger. 
     
     
         13 . The improved modular part of  claim 8 , wherein the selected trigger assembly comprises a guide wire trigger. 
     
     
         14 . The improved modular part of  claim 8 , wherein the part is comprised of any material suitable for use in a firearm. 
     
     
         15 . The improved modular part of  claim 8 , wherein the selected trigger assembly is selected from one or more different types of trigger assemblies. 
     
     
         16 . The improved modular part of  claim 8 , wherein the part is suitable for being installed in a variety of different types of firearm configurations. 
     
     
         17 . A firearm comprising a modular multifunctional part suitable for being installed on a variety of different types of firearm configurations, the multifunctional part being configured to house a selected firing control assembly and to interact with a selected trigger assembly. 
     
     
         18 . The firearm of  claim 17 , further comprising a housing for the modular multifunctional part, wherein the housing comprises any material suitable for use in a firearm. 
     
     
         19 . The firearm of  claim 17 , wherein the modular multifunctional part comprises any material suitable for use in a firearm. 
     
     
         20 . The firearm of  claim 17 , wherein the firearm comprises a pistol.
