Abstract:
A system for connecting a barrel to an upper receiver of a modular rifle, the upper receiver having an upper receiver extension. The system comprises an upper receiver coupler having a first opening for receiving the upper receiver extension, which is removably secured in the first opening. The system includes a barrel coupler and a gas tube for attaching to a forward segment of the barrel, extending rearwardly along the barrel, passing through a second opening of the barrel coupler and coupled to a gas port that extends from the upper receiver and into the upper receiver coupler. The gas tube is shorter than the barrel. The barrel passes through and is removably secured within a third opening of the barrel coupler; passes through the first opening of the upper receiver coupler and into the upper receiver extension. The upper receiver coupler and the barrel coupler are removably connected.

Claim (Index 15):
