Bipod for a small arms weapon, variably selectable surface interface apparatus, and method for reconfiguring same

A bipod for a small arms weapon comprising:

• a head portion for connecting to a small arms weapon;
• a first leg assembly connected to the head portion, the first leg assembly comprising
• a first elongated member, and
• a first variably selectable surface interface connected to the first elongated member, the first variably selectable surface interface comprising
• a first anchor interlocked with the first elongated member, and
• a first body secured to the first anchor, the first body comprising
• a proximal receptacle for mating with the first anchor,
• a distal opening spaced from the proximal receptacle along a first longitudinal axis, and
• a starboard axial bore adjacent to the proximal receptacle and the distal opening, the starboard axial bore comprising a second longitudinal axis, the second longitudinal axis being transverse to the first longitudinal axis, the starboard axial bore and the articulating surface interface comprising a joint such that the articulating surface interface oscillates about the second longitudinal axis;
• and
• a first distal support member pivotably connected to the first body to form a first pivot axis about which the first distal support member is free to oscillate, the first pivot axis being transverse to the first longitudinal axis, the first distal support member comprising a first articulating surface interface and a first control mechanism for selectively fixing the first articulating surface interface with respect to the first body, the first control mechanism comprising
• a first disperse load bearing configuration such that the first variably selectable surface interface is arranged with respect to the first body to form a first disperse load-bearing support, and
• a first point force load bearing support configuration such that the first variably selectable surface interface is arranged with the first body to form a first point force load bearing support.
