Abstract
Components of a firearm having a bolt with locking lugs improve shooting accuracy, due to increased coaxial alignment between the bolt, the cartridge, the receiver, and/or the barrel of a firearm. The receiver inner surface is shaped for lug-cleaning and for close tolerance/mating with the lugs only in the locked position and also with a non-threaded, axial surface of the barrel. Thus, the mating surfaces that are instrumental and/or that mainly control coaxial alignment of the receiver, bolt, and barrel are located between the lug stops and the threaded end of the receiver. The lugs may be axially curved or otherwise axially non-linear to tolerate dirt and other debris in a field environment.
