         2 . The firearm support of  claim 1 , wherein said at least two legs are each operably attached to said main body assembly by an indexer assembly configured to control an angular rotation of said at least two legs about said main body assembly. 
     
     
         3 . The firearm support of  claim 1 , wherein said at least two legs each comprise a telescoping assembly operable to extend and retract said at least two legs. 
     
     
         4 . The firearm support of  claim 3 , wherein each telescoping assembly has a plurality of indexed positions. 
     
     
         5 . The firearm support of  claim 1 , further comprising a cant locking mechanism comprising a locking plate and a threaded element such as a thumb screw or a locking lever operable to clamp said main body between said locking plate and said mounting assembly. 
     
     
         6 . The firearm support of  claim 5 , wherein said locking plate includes a level indicator. 
     
     
         7 . The firearm support of  claim 5 , wherein said threaded element is captive. 
     
     
         8 . The firearm support of  claim 1 , wherein said swivel mechanism comprises a first plate that stays fixed in relation to said firearm, a second plate configured to rotate parallel to said first plate around said swivel axis and a swivel locking assembly configured to move between a swivel locked position and a swivel unlocked position. 
     
     
         9 . The firearm support of  claim 8 , wherein said swivel mechanism comprises a means to limit the angular rotation of said second plate around said swivel axis. 
     
     
         10 . The firearm support of  claim 1 , wherein said attachment mechanism comprises a mounting base having a rail-engaging clamp member and at least one locking lever being mounted to said mount base and being moveable to a clamping position, whereby clamping engagement with said mount rail is established, and to a released position, whereby clamping engagement with said mount rail is released. 
     
     
         11 . The firearm support of  claim 1 , wherein each of said at least two legs further comprises a removable support foot attached to said outer leg. 
     
     
         12 . A firearm support, comprising:
 a cant mechanism operable to control an angular rotation about a cant axis; and   a swivel mechanism operable to control an angular rotation about a swivel axis;   wherein said cant mechanism is independent of said swivel mechanism and is located below said swivel mechanism.   
     
     
         13 . A firearm support, comprising:
 a main body assembly;   a mounting assembly comprising an attachment mechanism operable to attach a firearm to said mounting assembly and a swivel mechanism configured to control an angular rotation about a swivel axis;   a cant mechanism operable to control an angular rotation about a cant axis, wherein said cant mechanism is created by rotating said mounting assembly along at least one opening in said main body assembly, whereby swivel and cant may be adjusted independently; and   at least two legs operably attached to said main body assembly; wherein said at least two legs are each operably attached to said main body assembly by an indexer assembly configured to control an angular rotation of said at least two legs about said main body assembly; and wherein each indexer assembly comprises a spring loaded button that allows said leg to be released from its indexed position, and wherein said button can be pushed to release said indexed position; and   wherein said at least two legs each comprise a telescoping assembly operable to extend and retract said at least two legs, wherein each telescoping assembly has a plurality of indexed positions.   
     
     
         14 . A firearm support, comprising:
 a main body assembly;   at least two legs operably attached to said main body assembly; wherein said at least two legs each comprise a telescoping assembly operable to extend and retract said at least two legs, and wherein each telescoping assembly comprises an outer leg further comprising one or two button openings that are perpendicular to the outer leg axis and concentric to each other, an inner leg at least partially disposed within said outer leg and operable to extend and retract relative to said outer leg, said inner leg to comprising a plurality of indexing notches; and   a spring loaded release button assembly disposed through said button openings, wherein said release button assembly only protrudes from said outer leg, if at all, through said outer leg button openings; and wherein said release button is operable to slide within at least one of said plurality of indexing notches so as to block the movement of said outer leg in relation to said inner leg, or when depressed to slide out of said notches so as to allow said outer leg to extend and retract relative to said inner leg.   
     
     
         15 . The firearm support of  claim 14 , wherein each of said at least two legs further comprises a removable support foot attached to said outer leg. 
     
     
         16 . A firearm support, comprising:
 a main body assembly;   at least two legs operably attached to said main body assembly;   a cant mechanism operable to control an angular rotation about a cant axis; and   a level indicator.   
     
     
         17 . The firearm support of  claim 16 , wherein said level indicator comprises a ball guided in a cavity filled with a liquid, wherein said ball is guided between at least two surfaces, two of which are concentric with said cant axis. 
     
     
         18 . The firearm support of  claim 16 , further comprising a swivel mechanism operable to control an angular rotation about a swivel axis.
