Abstract A firearm can have a bolt having a plurality of locking lugs that are configured to have a shear area that is larger than that of a standard M16/M4. A bolt carrier can have a bolt that has a double cut cam having an unlocking cam surface that has sufficient dwell increase to delay a start of unlocking when the bolt carrier is used in an M4 carbine. A stepped extractor pin may be provided that prevents disengagement of the extractor pin. A tube can be configured to provide gas from a barrel of the firearm to the piston via the carrier key. The tube can have a heat radiator formed from triangular shaped threads on at least a portion of the tube. A piston on the bolt and can have a plurality of rings including pairs of mating rings that are formed and maintained as a matched pair. Une arme à feu peut être dotée dune culasse comptant une vaste gamme de tenons de verrouillage configurés afin davoir une zone de cisaillement plus importante que celle dune M16/M4 habituelle. Un porte-culasse peut avoir un boulon qui a une came à double découpe ayant une surface de came de déverrouillage qui a une augmentation suffisante du maintien pour retarder un début de déverrouillage lorsque le porte-culasse est utilisé dans une carabine M4. Une broche d'extraction étagée peut être prévue pour éviter le désengagement de la broche d'extraction. Un tube peut être configuré pour fournir du gaz d'un canon de l'arme à feu au piston via la clé porteuse. Le tube peut comporter un radiateur thermique formé de fils de forme triangulaire sur au moins une partie du tube. Un piston sur le pêne et peut comporter une pluralité de bagues comportant des paires de bagues d'accouplement qui sont formées et maintenues en paire appariée.
