Cam slot for firearm

Abstract

Provided herein are bolt carriers, firearms, and related methods, devices, and assemblies. A bolt carrier for a firearm of an example embodiment includes a cam slot configured to receive a cam pin of a bolt, the cam slot defining a cam path along which the cam pin is configured to travel, the cam path comprising a locked dwell, an unlocked dwell, and a transition section disposed between the locked dwell and the unlocked dwell, wherein the locked dwell defines a portion parallel to a first axis of the bolt carrier that is greater than 0.070 inches long.

1 . A bolt for a firearm, the bolt comprising:
 an elongate body, a muzzle end of the elongate body defining one or more bolt lugs; and   a cam pin operably coupled to and extending from the bolt,   wherein the cam pin is disposed on the bolt at a position farther from the one or more bolt lugs than a standard cam pin and bolt configuration of a Technical Data Package (TDP) corresponding to a type of the firearm.   
     
     
         2 . The bolt of  claim 1 , wherein the cam pin is disposed approximately 0.064 inches farther from the one or more bolt lugs than the standard cam pin and bolt configuration of the TDP. 
     
     
         3 . The bolt of  claim 1 , wherein a distance between the cam pin and a rearward edge of the one or more bolt lugs is approximately 1.216 inches. 
     
     
         4 . A bolt carrier group for a firearm, the bolt carrier group comprising:
 a bolt carrier defining an interior; and   a bolt defining one or more bolt lugs,   wherein at least a portion of the bolt is disposed in the interior of the bolt carrier to permit the bolt to translate along and rotate about a first axis of the bolt carrier,   wherein a cam pin is operably coupled to and extends from the bolt, and   wherein the cam pin is disposed on the bolt at a position farther from the one or more bolt lugs than a standard cam pin and bolt configuration of a Technical Data Package (TDP) corresponding to a type of the firearm.   
     
     
         5 . The bolt carrier group of  claim 4 , wherein the cam pin is disposed approximately 0.064 inches farther from the one or more bolt lugs than the standard cam pin and bolt configuration of the TDP. 
     
     
         6 . The bolt carrier group of  claim 4 , wherein a distance between the cam pin and a rearward edge of the one or more bolt lugs is approximately 1.216 inches. 
     
     
         7 . The bolt carrier group of  claim 4 , wherein the bolt carrier further defines a cam slot, the cam slot being defined between the interior of the bolt carrier and an exterior of the bolt carrier, and wherein the cam slot is configured to constrain the translation and rotation of the bolt, the cam slot defining a cam path along which the cam pin is configured to travel, the cam path comprising a locked dwell, an unlocked dwell, and a transition section disposed between the locked dwell and the unlocked dwell. 
     
     
         8 . The bolt carrier group of  claim 7 , wherein the cam slot is disposed closer to a muzzle end of the bolt carrier than a standard cam slot of the TDP. 
     
     
         9 . The bolt carrier group of  claim 7 , wherein the locked dwell is greater than a standard locked dwell. 
     
     
         10 . The bolt carrier group of  claim 9 , wherein the locked dwell defines a portion parallel to the first axis that is greater than 0.070 inches long. 
     
     
         11 . The bolt carrier group of  claim 9 , wherein the locked dwell is approximately 0.195 inches. 
     
     
         12 . The bolt carrier group of  claim 9 , wherein in operation, the bolt is configured to move between a locked position and an unlocked position,
 wherein in the locked position, the cam pin is configured to be disposed at or proximate a buttstock end of the cam slot, and   wherein in the unlocked position, the cam pin is configured to be disposed at or proximate a muzzle end of the cam slot.   
     
     
         13 . The bolt carrier group of  claim 12 , wherein in the locked position, the cam pin is disposed approximately 1.002 inches from a muzzle end of the bolt carrier. 
     
     
         14 . The bolt carrier group of  claim 12 , wherein in the unlocked position, a rearward edge of the one or more bolt lugs is disposed approximately 0.638 inches from a muzzle end of the bolt carrier. 
     
     
         15 . The bolt carrier group of  claim 12 , wherein in the unlocked position, the cam pin is disposed approximately 0.578 inches from a muzzle end of the bolt carrier.
