Abstract

An indirect gas operating system for an M4 type automatic or semi-automatic firearm. The indirect gas operating system has a gas block having a cylinder. The gas block is fitted to a barrel assembly having a bore with the cylinder in communication with the bore. A piston having a piston end and a striking end has the piston end fitted to the cylinder. A bolt assembly having a striking surface is provided. When a cartridge is fired, gas displaces the piston end and causes the striking end to strike the striking surface displacing the bolt assembly. The cylinder and the piston are together removable as an assembly from the firearm without removal of the gas block.
L'invention concerne un système de fonctionnement à gaz indirect pour une arme à feu automatique ou semi-automatique du type M4. Le système de fonctionnement à gaz indirect possède une frette de gaz à un cylindre. La frette de gaz est ajustée sur un ensemble canon présentant un alésage avec le cylindre en communication avec l'alésage. L'extrémité de piston d'un piston ayant une extrémité de piston et une extrémité de percussion est ajustée sur le cylindre. Un ensemble de verrou ayant une surface de percussion est fourni. Lorsqu'une cartouche est tirée, le gaz déplace l'extrémité de piston et amène l'extrémité de percussion à frapper la surface de percussion, en déplaçant l'ensemble de verrou. Le cylindre et le piston peuvent être enlevés ensemble de l'arme à feu, sous la forme d'un ensemble, sans enlever la frette de gaz.
