Tippmann 98 Custom Act Paintball Gun - Page 3 - Answered Questions & Fixed issues

If you **** it you may find that that stops. Or **** it and then screw in your tank. Make sure you have plenty of air in the tank too, low pressure can sometimes not engage the valve enough to close.

My first suggestion is to pull out the internals and clean/lube them with a good oil made for paintball.

It's possible it could be an o-ring, but I'd try the above first. If it's been a while since you've had any o-rings replaced it might be a good time for a tuneup. Get a kit and change 'em all and you know everything is good to go rather than waiting for something to fail.. and if one fails it's probably only a matter of time before another one gives.

Good luck!

The sear and pin can certainly "look" fine but still be a fraction off and let the marker loose. Also, you may notice that the pin on the sear is different than the others? Perhaps silver where the others are black?

My best advice at this point would be to check with a buddy who's willing to let you exchange the sear and pin and see if that's the problem, or check with a local airsmith who can try this for you and check for any other problems as well.

Good luck!

No, you didn't do anything wrong...

Paintballs come in a variety of sizes. That difference is very hard to see with the naked eye, but your barrel knows what fits and what doesn't. Players have a choice in barrels and ID-internal dimensions, so the balls are various sizes as well. You will have to sample a few brands and see what works best for you.

Good luck!

**** it and that should stop.

If that persists make sure you have cleaned the marker and used a good paintball oil to lubricate the internals.

At the next level you could have a o-ring that's old, brittle, broken and now is leaking by. Your local airsmith should be able to provide the necessary part(s) or fix it in short order for you.

Good luck!

There's a spring clip that goes in the little latch. Apparently that's either slipped on one end, or missing entirely. It very easy to lose that ****** when you're breaking down the marker for cleaning.

If you're missing the spring, check with your local airsmith or paintball field/shop to see if they have this part. If not, Tippmann would undoubtedly have one available. I have them in my master kits as a stock item.

Good luck!! In the future, when you're breaking down the marker, try to lay it on a white cloth/towel or something you can see all the parts, especially if something falls off that you weren't intending to remove. In this case, it could have sprung off into a random direction at a high rate of speed and be gone to the winds... you'll be able to watch for it next time.

You are correct. Cold (and heat) play a part in expanding the parts of your marker. In cold weather, plus the coldness of the co2 working through it, the various parts can and will expand and contract at different rates. It only takes a fraction of inch to leak.

First thing is to make sure you have thoroughly cleaned and LUBED your marker. Lubrication... what kind of oil are you using? Some general purpose oils may work well enough in better weather, but in cold weather, and especially when using co2, you would be well advised to find and use an oil specific to paintball markers. These are manufactured with COLD in mind and will continue to work where others will gel up.

So yes, you are correct in your assessment. Keep your marker covered up when you're at the staging area... uncover it to chrono or test fire it at the range.. or when you get ready to roll out to the field. Use a good, paintball-specific lube (and keep it clean and lubed).

Also... an o-ring isn't just an o-ring. They have different densities and much like the proper lube, you need o-rings that are specific to the task at hand. Cold is a killer and it loves to mess with rubber and plastic. An o-ring that's become hard and brittle can't do a good job, so don't get o-rings from just any old place because they're cheap and look like they'll fit. Use good parts, good lube, and you should get some better performance out there.

Good luck... play hard, play safe, play with honor!

Go to ebay and buy a new ball detent for the 98 they are cheap and well worth it because how many times have you got shot for double balling :)

Check the O rings on the big metal striker, make sure that you have the spring on the back (where the stock would have went) in the right hole on the back plate. Make sure that your velocity is set to a reasonable level.

if there is a 9 volt battery in the handle, there should be 3 to 5 small dip switchesright by the battery, your set on 3 shot burst, unhook the gas, turn all switches off, and test it, there is also a full auto setting, try different combinations untill you get single shot

How To reassemble an Army alpha black paintball gun.

Put a piece of wood behind the trigger. That should stop it, or simply remove the ammo.

Yes, you can use a compressed air tank on a Tippmann 98 custom. 48ci 3K psi tanks can be purchased for around $30.

Your "ball detent" has worn out. This is a little rubber nipple inside the breech of your gun (where the balls go into the gun from your hopper) that has torn. This is a normal wear and tear item and will cost you only a few dollars to repair. You have to buy this part from your local paintball pro shop they will have it.

make sure you replace all of the internal o-rings for commpression. one may be worn slightly and contracts when cold allowing gas to escape

yes . take your time and sand to fit,

I have the exact same gun. Looking at the gun, barrel facing left. You'll see the word Tippmann. Just below and slightly right of the end of that word you will see a allen head screw. Using and allen wrench turn that screw. If you wish to raise the velocity, tighten the screw. If you wish to slow the balls down, loosen the screw (bring it out, but not too far.) The faster the paint balls go though, they have a tendency to burst (but not usually) or the big thing with mine, is they get more back spin, and they travel UP, making them also go further. If they go to slow, they are pretty inaccurate. I find my optimum performance, when the allen screw is flush with the plastic on the outside of the weapon. Hope this helps!

There are pdf manuals on the Tippmann website.

If you ran out of air, it won't stay cocked.
OR
The sear may have been displaced. That would require a disassemble. It is not that difficult, just do it on a white pillowcase and be sure not to let any springs fly all over the place.

No O-rings are used to change volocity on Tippmann Markers. The velocity screw is on the left side and is turned clockwise to decrease and CCW to increase velocity. Typically if you turn the screw in till it stops then turn it back 2 turns the gun will shoot about 280FPS.

Lay it on the ground, gently pull the hoop and turn the screw.
