The invention claimed is: 1. A telescoping leg for a firearm, the telescoping leg comprising: a housing, a first telescoping portion mounted inside the housing, and a second telescoping portion mounted inside the first telescoping portion; a first release button mounted in said housing for releasin
The invention claimed is: 1. A telescoping leg for a firearm, the telescoping leg comprising: a housing, a first telescoping portion mounted inside the housing, and a second telescoping portion mounted inside the first telescoping portion; a first release button mounted in said housing for releasing said first telescoping portion; a second release button mounted in said housing for releasing said second telescoping portion; and a screw thread portion for rotation of said housing about said second telescoping portion, for adjustment of the length of the leg while said second telescoping portion rests on a solid support. 2. The telescoping leg according to claim 1, wherein said first telescoping portion is spring loaded inside the housing, said first release button permitting said first telescoping portion to extend under urging of said spring. 3. The telescoping leg according to claim 2, wherein said second telescoping portion is spring loaded inside the first telescoping portion, said second release button permitting said second telescoping portion to extend under urging of said spring. 4. The telescoping leg according to claim 3, further comprising a pivot and locking mechanism permitting the leg to be pivoted and locked in each of several different positions, including a folded position adjacent a stock of the firearm, a fully open position substantially perpendicular to the folded position, and at least one stable intermediate shooting position between the folded position and the fully open position. 5. The telescoping leg according to claim 4, wherein said pivot and locking mechanism comprises: a head portion having a plurality of dimples; a complementary ball mounted in said stock; whereby pivoting of the leg relative to said stock causes said ball to move between said dimples and to releasably lock in a selected dimple. 6. The stock according to claim 3, wherein said telescoping leg further comprises a pair of springs, one said spring biasing said first telescoping portion inside said housing; and said second spring biasing said second telescoping portion inside said first telescoping portion. 7. The stock according to claim 3, wherein said telescoping leg further comprises a spring biasing said first telescoping portion inside said housing; said spring also biasing said second telescoping portion inside said first telescoping portion. 8. The telescoping leg according to claim 1, further comprising a pivot and locking mechanism permitting the leg to be pivoted and locked in each of several different positions, including a folded position adjacent a stock of the firearm, a fully open position substantially perpendicular to the folded position, and at least one stable intermediate shooting position between the folded position and the fully open position. 9. The telescoping leg according to claim 8, wherein said pivot and locking mechanism comprises: a head portion having a plurality of dimples; a complementary ball mounted in said stock; whereby pivoting of the leg relative to said stock causes said ball to move between said dimples and to releasably lock in a selected dimple. 10. A stock for a firearm, including a telescoping leg, said leg comprising: a housing, a first telescoping portion mounted inside said housing; means for extending said first telescoping portion; a second telescoping portion mounted inside said first telescoping portion; and means for extending said second telescoping portion; a first release button mounted in said housing for releasing said first telescoping portion; a second release button mounted in said housing for releasing said second telescoping portion; and a screw thread portion for rotation of said housing about said second portion, for adjustment of the length of the leg while said second telescoping portion rests on a solid support. 11. The stock according to claim 10, wherein said telescoping leg further comprises a pair of springs, one said spring biasing said first telescoping portion inside said housing, said first release button permitting said first telescoping portion to extend under urging of said first spring; and said second spring biasing said second telescoping portion inside said first telescoping portion, said second release button permitting said second telescoping portion to extend under urging of said second spring. 12. The stock according to claim 10, wherein said telescoping leg further comprises a spring biasing said first telescoping portion inside said housing; said spring also biasing said second telescoping portion inside said first telescoping portion. 13. A method for forming a telescoping leg for a firearm, the method comprising: mounting a first telescoping portion inside a housing; providing means for extending said first telescoping portion; mounting a second telescoping portion inside said first telescoping portion; providing means for extending said second telescoping portion; forming screw threads on said housing, said first telescoping portion and said second telescoping portion; and rotating said housing about said second telescoping portion for adjusting a length of the leg while said second telescoping portion rests on a solid support. 14. The method according to claim 13, wherein said step of mounting a first telescoping portion includes spring biasing said first telescoping portion inside said housing for release by said means for extending said first portion and said step of mounting a second telescoping portion includes spring biasing said second telescoping portion inside said first telescoping portion for release by said means for extending said second portion. 15. The method according to claim 14, wherein said step of mounting a first telescoping portion includes providing a first spring for biasing said first telescoping portion inside said housing; and said step of mounting a second telescoping portion includes providing a second spring for biasing said second telescoping portion inside said first telescoping portion. 16. The method according to claim 14, wherein steps of mounting a first telescoping portion and a second telescoping portion include providing a spring for biasing both said first telescoping portion inside said housing; and for biasing said second telescoping portion inside said first telescoping portion.
