Abstract
An M-4 type firearm is provided. The M-4 type firearm having a receiver with a bolt carrier movably located therein. A receiver extension is connected to the receiver with the receiver extension including a spring loaded bolt carrier buffer movable relative to the receiver for effecting return of the bolt carrier to a firing position of the bolt carrier. A regulator is provided on the receiver extension, for enabling movement of the bolt carrier buffer relative to the receiver and effecting automatic or semi-automatic fire when the receiver extension is at least partially filled with water.
Claims22
An M-4 type firearm comprising:
- a receiver with a bolt carrier movably located therein;
- a receiver extension connected to the receiver, the receiver extension including a spring loaded bolt carrier buffer movable relative to the receiver for effecting return of the bolt carrier to a firing position of the bolt carrier;
- and
- a regulator, on the receiver extension, for enabling movement of the bolt carrier buffer relative to the receiver and effecting automatic or semi-automatic fire when the receiver extension is at least partially filled with water.
An M-4 type firearm comprising:
- a receiver with a bolt carrier movably located therein;
- a receiver extension connected to the receiver, the receiver extension enclosing a bolt carrier return spring;
- and
- a regulator valve coupled to the receiver extension;
- wherein, the bolt carrier return spring effects return of the bolt carrier to a firing position, and wherein, the regulator valve regulates a firing rate of the firearm.
An M-4 type firearm comprising:
- a receiver having a bolt carrier movably located therein;
- a barrel coupled to the receiver;
- a receiver extension connected to the receiver, the receiver extension having a bolt carrier return spring;
- an indirect gas operating system coupled to the barrel;
- and
- a cycle rate selector mounted on the receiver extension;
- wherein, the indirect gas operating system and the bolt carrier return spring cooperate to cycle the bolt carrier in the receiver, and wherein, the cycle rate selector regulates automatic firing cycle rate of the firearm.
An automatic firearm comprising:
- a receiver having a bolt carrier movably located in an interior of the receiver;
- a receiver extension connected to the receiver, the receiver extension having an interior passage through which the interior of the receiver communicates with an exterior of the firearm;
- a closure coupled to the receiver extension, the closure being selectably movable between opened and closed positions;
- wherein, the closure in the closed position is more restrictive on fluid flow through the interior passage than when the closure is in the opened position.
