Tippmann 98 Custom - Make that trigger pull extra light!
A lot of you, lately, have been asking how to reduce the trigger pull of your Tippmann 98. And boy oh boy do I remember the day when it felt like I was lifting weights with my fingers just to get it firing. So what have I done? I've taken a couple pictures (and time) to put together a little, simple, and short, step-by-step instructions for getting you pull nice and light. I've also included a video of what you can expect by doing this at the end of the post.
I am not liable for any damage you cause to your marker.
Dissassemble your marker. This, of course, is done by unscrewing the six body screws and taking off the reciever. After doing this, you should be looking at the internals of your gun. Here's a picture of what you're going to be taking apart / messing with.
Take out the spring to the far left. This an unnecessary spring that just makes it annoying to fire
Bad bad bad. If you like the feel of it, you can always put in a lighter pen spring later.
Speaking of pen springs... go find yourself a pen and wire cutters! Right? Good. Now take apart the pen and grab the spring inside. Some of them have smaller size springs, some have larger ones. I like the really long ones because using them allows me to cut to whatever length I want. Generally, they're lighter as well.
So now that you have a spring from a pen and some cutters to trim it once you're ready... why don't you go ahead and take out the trigger. As you can see, there is a metal sleeve on the back-end. In this sleeve is a really heavy spring, exactly identical to the one that we took out from the front of the trigger earlier. There's a punch pin that holds this sleeve in place. Get something to push it out --- that pen you stole the spring from should work wonders. Careful though, there's a lot of tension and it'll shoot out once the pin is released, make sure not to lose anything
When you're done, it should look like this:
Now here's the part that is up to you, and I'm just going to throw up into the air --- you have a replacement spring... chances are it's either too long or too heavy (yep, even that small pen spring is pretty heavy) for the pull to feel nice and light in the end. Go ahead and cut it. Experiment. Remember - it's better to cut too little than too much. You can always re-assemble the trigger and feel the tension by pushing on the sleeve. Don't make it too light - some tension is needed... and if there isn't enough then you won't be able to fire.
Once you get the desired amount of spring tension, put the sleeve back on and place the pin in the trigger. Yay! Only one more thing to do!
Now here comes the part that really smoothens out your pull. The sear spring. If you look back at the first picture, it is the spring to the far right that is connected to the sear and one of the lower trigger pins. The stock sear spring is pretty heavy, and accounts for most of the pressure needed to make the marker fire. Let's go ahead and have some fun with it.
Some people say to replace the sear with an ortho band or what have you, but the fact is that these replacements can often break. You don't want a break in the middle of a game to leave you shuddering behind a bunker waiting to get barrel tagged, do you? Let's just stick with the stock one and 'modify' it a little bit instead.
This is the one part where you can actually screw up your sear spring if you aren't careful.
If you do, you're going to have to buy a new one. This shouldn't happen if you follow the instructions... so just be good.
--> Take the sear spring off of the sear.
--> Take a pair or two of plyers and attach each loop inside them
--> Pull... just a little bit.
--> Put sear spring back into normal position
--> Put reciever half onto gun, cock, fire
Alternative - especially if your sear spring is too stretched
If you don't pull too much, you'll see a difference. The more times you do this the less of a pull you'll get. So long as you're careful and take your time in stretching the spring, you should get an idea of when too much is just enough (har har). Just take it one step and a little bit at a time.
When you're done, put everything back in place and put the gun back together. Voila! Gas it up and get it going! You'll be amazed how less than fifteen minutes can so drastically increase your rate of fire.
With some fine tuning, a double trigger, and a springkit you can create a mechanical 98 walkable.
