Anti jam, grooved and expanding charging handle for sub caliber actions

1. A telescopic charging handle incorporated into an upper receiver of an AR-15 firearm, comprising:

a first stem portion integrally formed with a handle shaped head;

a second stem portion terminating at a distal end in a projecting beak and further being telescopically engaged at a proximal end to said first stem portion; and

said second stem portion further having a reduced dimension portion which is sized to seat within a communicating distal and interiorly open end of said first stem portion, a distal end located and widthwise extending aperture in said second stem portion which aligns with slots in said first stem portion and, upon insertion of a widthwise pin, is telescopically mounted between the fully collapsed and extended positions;

said charging handle extending upon being rearwardly displaced in order to accommodate a modified length sub caliber action.

2. The handle as described in claim 1 , wherein said slots comprise a pair of linear slots extending a given distance along said first stem portion.

3. The handle as described in claim 1 , said beak associated with said second stem portion further comprising an underside extending and sub caliber action engaging beak.

4. The handle as described in claim 1 , further comprising a pair of wing projections extending in opposite fashion from a distal end of said second stem portion.

5. A charging handle incorporated into an upper receiver of an AR-15 firearm, comprising:

a stem integrally formed with a handle shaped head; and

a reduced profile recess configured along said stem for preventing jamming of spent shell casings;

said stem further including a first stem portion integrally formed with a handle shaped head and a second stem portion terminating at a distal end in a projecting beak and further being telescopically engaged at a proximal end to said first stem portion;

said charging handle extending upon being rearwardly displaced in order to accommodate a modified length sub caliber action;

said second stem portion further comprising a reduced dimension portion which is sized to seat within a communicating distal and interiorly open end of said first stem portion; and

a distal end located and widthwise extending aperture in said second stem portion which aligns with slots in said first stem portion and, upon insertion of a widthwise pin, is telescopically mounted between the fully collapsed and extended positions.

6. The handle as described in claim 5 , wherein said slots comprise a pair of linear slots extending a given distance along said first stem portion.

7. The handle as described in claim 5 , said beak associated with said second stem portion further comprising an underside extending and sub caliber action engaging beak.

8. The handle as described in claim 5 , further comprising a pair of wing projections extending in opposite fashion from a distal end of said second stem portion.

9. A telescopic charging handle incorporated into an upper receiver of an AR-15 firearm, comprising:

a first stem portion integrally formed with a handle shaped head;

a pair of linear extending slots extending a given distance along said first stem portion;

a second stem portion terminating at a distal end in a projecting beak, said second stem portion having a reduced dimension and extending portion which is sized to seat within a communicating distal and interiorly open end of said first stem portion for telescopically inter-engaging said first and second stem portions between collapsed and lengthwise extended positions;

a distal located and widthwise extending aperture in said second stem portion which aligns with said slots in said first stem portion, a widthwise pin inserting through said aperture for establishing a lengthwise extensible range along said aligning slots; and

said charging handle extending upon being rearwardly displaced in order to accommodate a modified length sub caliber action.

10. The handle as described in claim 9 , said beak associated with said second stem portion further comprising an underside extending and sub caliber action engaging beak.

11. The handle as described in claim 9 , further comprising a pair of wing projections extending in opposite fashion from a distal end of said second stem portion.
