Never seen that setup before , but I do see two reasons to stay away from it . 1 the front sight is plastic , they don't last long in the woods , too fragile ! 2 rear sight aperture is too far from the eye , one of the pluses of a peep sight is a longer sight plain . That setup will probably be useless in low light . If you want a fiber optic front , get a Williams Fire Sight ! A Williams rear such as the 5d or Fool Proof or even a guide if your gun is angle eject !
