Tippmann 98 custom w/ pb double trigger and pb drop.
When i took apart the gun to put this new trigger in all i had to do was take out the old trigger and guard and place the pb trigger and guard in and put the gun back together. That's it!
Very easy to install
Nice grade materials-not flimsy
Lighter and shorter trigger pull-good compensation for not getting rt trigger
Don't have to cut grips
Nothing that i can think of
Very good if you want to get a faster rate of fire but don't want to spend money on the rt trigger get this. Very good product from pb!
