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 20):
A weapon comprising:\n an upper receiver defining a gas port and a barrel opening, the barrel opening extending through a threaded upper receiver extension; a barrel; an upper receiver coupler, the threaded upper receiver extension extending through a first opening defined in the upper receiver coupler; a threaded component for threadably engaging and attaching the threaded upper receiver extension to the upper receiver coupler and thereby to the upper receiver; a barrel coupler defining a second opening for receiving the barrel, the barrel secured within the second opening and into the barrel opening in the upper receiver extension; a gas tube having a length less than a length of the barrel; a gas key having a first end attached to the upper receiver and a second end extending into a third opening defined in the receiver coupler; a forward end of the gas tube attached to a forward end of the barrel; a rearward end of the gas tube extending through a fourth opening in the barrel coupler and attached to the second end of the gas key for creating a continuous gas flow path from the forward end of the barrel to the upper receiver; and the upper receiver coupler attached to the barrel coupler.
