Adaptive configuration for a firearm
A combination for a firearm which creates an improved firearm. An upper chassis is created which is formed from a first housing and a second housing which, once independently formed, are permanently secured to each other. The upper chassis provides a first opening through which a spent cartridge is discharged and a second opening which permits a variety of attachments to be selectively attached to the upper chassis to customize the firearm to the user and activity.
1. A firearm having a barrel, an action mechanism, and means for discharging a spent cartridge from said barrel, said firearm comprising:
a) A first housing having,
1) a first opening through which the spent cartridge is discharged,
2) an mounting rail, and,
3) a threaded member positioned to secure the barrel to the first housing; and,
b) a second housing having a mounting rail, and wherein said second housing is secured to said first housing such that the mounting rail of said first housing is longitudinally aligned with the mounting rails of said second housing.
2. The firearm according to claim 1 , further including a third housing securable to the second housing such that, when secured to each other, said second housing and said third housing form a channel.
3. The firearm according to claim 2 , wherein the mounting rail of said first housing and the mounting rail of the second housing are machined to form a single continuous mounting rail.
4. The firearm according to claim 3 , further including a threaded nut adapted to selectively secure the first housing to the action mechanism via said threaded member.
5. The firearm according to claim 4 , wherein when said first housing is secured to the action mechanism and said barrel is secured to said action mechanism via said threaded member as the threaded nut, said second housing and said third housing encircle said barrel without contacting the barrel.
6. A chassis for a firearm having a barrel and an action mechanism, said chassis comprising:
a) a first housing having,
1) a first opening through which a spent cartridge is discharged from said action mechanism when said first housing is secured to said firearm, and,
2) a second opening accessing the action mechanism when said first housing is secure to said firearm; and,
b) an attachment securable to the first housing such that said attachment at least partially obscures said second opening when said attachment is secured to said first housing.
7. The chassis according to claim 6 , wherein said attachment includes a deflection plate positioned to deflect the spent cartridge exiting from said first opening in said housing.
8. The chassis according to claim 6 , wherein said attachment includes a manually operable bolt mechanism selectively engaging said action mechanism.
9. The chassis according to claim 8 , wherein said first housing further includes:
a) an mounting rail; and,
b) a threaded member positioned to secure the barrel to said action mechanism when said first housing is secured to the action mechanism.
10. The chassis according to claim 9 , further including:
a) a second housing having an mounting rail, and wherein said second housing is permanently secured to said first housing such that the mounting rail of said first housing is longitudinally aligned with the mounting rail of said second housing; and,
b) a third housing securable to the second housing such that, when secured to each other, said second housing and said third housing form a channel through which the barrel of said firearm passes.
11. The chassis according to claim 10 , wherein the mounting rails of said first housing and the mounting rail of said second housing are machined to form a single continuous mounting rail.
12. A combination for a firearm having a barrel, an action mechanism, and means for discharging a spent cartridge from said barrel, said combination comprising:
a) an upper chassis comprising,
1) a first housing having,
A) a first opening through which said spent cartridge is discharged,
B) a second opening accessing the action mechanism contained within said first housing,
C) a locking mechanism located on an exterior portion of said housing positioned proximate to the second opening
D) an mounting rail, and,
E) a threaded member positioned to secure said first housing to said action mechanism, and,
2) a second housing having an mounting rail, and permanently secured to said first housing such that the mounting rail of said first housing is longitudinally aligned with the mounting rail of said second housing;
b) a lower chassis selectively securable to the second housing of said upper chassis such that when secured to each other, said lower chassis and the upper chassis provide a channel through which a barrel of said firearm extends;
c) a first attachment securable to said first housing over said second opening and being a manually operable bolt mechanism for selectively engaging said action mechanism; and,
d) a second attachment securable to said first housing over said second opening and being a deflection plate positioned to deflect a spent cartridge exiting from said first opening in said housing.
13. The combination according to claim 12 , wherein the mounting rails of said first housing and the mounting rail of said second housing are milled to form a single continuous upper housing.
14. The combination according to claim 13 , wherein said first housing includes a threaded member configured to secure the barrel to the action mechanism.
