Abstract

The present invention is an improved charging handle for a firearm. The handle is generally non-reciprocating and features a user activated forward assist. The major components are an actuator to provide charging function and upon which other components are mounted, a spring biased lever with a hook which biases downward so that the hook may interface a bolt carrier when the lever is activated, and a blade upon which handle structure is mounted. In the preferred embodiment, the handle is ambidextrous and features a spring detent to keep it in stowed position until the user desires use. The handle will only reciprocate when the lever is activated, which in turn requires intentional user action, thereby providing a relatively safer weapon to operate.

Claims

1. A charging handle for a firearm comprising:

a. A charging handle actuator having a diagonal notch on a dorsal side, said notch extending downward and towards a fore end of the actuator;

b. A spring biased forward assist lever, residing on the dorsal side of the charging handle actuator and further comprising;

i. a fore end capable of manipulation against the spring bias;

ii. angled ears residing in the notch; and

iii. a hook residing aft of a distal end of the actuator; and

c. a charging handle blade residing on the dorsal side and towards the fore end of the charging handle actuator, said charging handle blade providing support for at least one user interface knob,

wherein, when the fore end of the forward assist lever is manipulated against the spring bias, the forward assist lever moves forward and the ears, and correspondingly the hook, are biased downward, allowing the hook to interface with a bolt carrier.

2. The charging handle of claim 1, further comprising a detent spring designed to interface with at least one detent notch located on support rails for the charging handle within the firearm.

3. The charging handle of claim 2, the charging handle actuator further comprising lateral retention means for the forward assist lever.

4. The charging handle of claim 3, the lateral retention means being a pair of ridges between which the forward assist lever resides, the detent notch extending though said ridges.

5. The charging handle of claim 1, the charging handle actuator further comprising lateral retention means for the forward assist lever.

6. The charging handle of claim 5, the lateral retention means being a pair of ridges between which the forward assist lever resides, the detent notch extending though said ridges.

7. The charging handle of claim 1, the fore end of the forward assist lever being T shaped, with each side of said T interfacing with one user interface knob and extending out from a left and right side of the charging handle, thereby providing ambidextrous use of the charging handle.

8. The charging handle of claim 7, further comprising a detent spring designed to interface with at least one detent notch located on support rails for the charging handle within the firearm.

9. The charging handle of claim 8, the charging handle actuator further comprising lateral retention means for the forward assist lever.

10. The charging handle of claim 9, the lateral retention means being a pair of ridges between which the forward assist lever resides, the detent notch extending though said ridges.

11. The charging handle of claim 7, the charging handle actuator further comprising lateral retention means for the forward assist lever.

12. The charging handle of claim 11, the lateral retention means being a pair of ridges between which the forward assist lever resides, the detent notch extending though said ridges.
