I recently purchased the tippmann a-5 double trigger. I wil say this is the best twenty dollars i have spent n my gun. Not only is this solution for a faster rof dirt cheap, it is almost just as effective as the Rt or Egrip. If you understand how to dismantle and reasemble your marker putting on this attachment will be a breeze.
Conclusion:
I love this trigger and I am glad tippmann made a cheaper way o increase rof other than the RT.
