摘要：
A firearm (20) including a receiver (30), a barrel (22) , a breech bolt assembly (42), and a trigger assembly (32). The bolt assembly (42) has a bolt (50)including a body portion (56), a lug portion (90), and a firing pin bore (44). The lug portion (90) includes outward extending lugs (110), a cartridge recess (92), and an off-center hole (96). The bolt assembly (42) also includes an extractor (46) and an ejector pin (98). At least some of the lugs (110) on the lug portion (90) of the bolt (42) have a tapering outer face (120) so that a rearward face (116) of the respective lug (110) is taller than a forward face (114) of the respective lug (110). In another embodiment, at least some of the lugs (110) on the lug portion (90) of the bolt (42) have tapering side faces (122,124) so that a rearward face (116) of the respective lug (110) is wider than a forward face (114) of the respective lug (110).
