All gas tubes are straight in the gas block area.  Accordingly, any FSB will work for what you are doing provided that the GB ID is the OD of your barrel are compatible.

straight gas tubes need a taller block, because they don't bend downward. putting a straight gas tube in a normal gas block would create a bend in it.

ETA N/M. You said FSB not gas block.

Rifle speed adjustable.
