The BC2.0 has the same exterior dimensions as an A2, but still has the same precision interior dimensions as the BC1.0 and BC1.5; and the identical performance you can expect from a BattleComp.
Accordingly, the BattleComp 2.0 is compatible with devices intended to integrate with an A2; but the BattleComp 2.0 is still the excellent compensator many of us have grown to love.
