Well, after a week of trying everything from CO2 to HPA, disassembling, cleaning, oiling, and various types of paintballs I returned my A-5 Stealth.

Shots were curving left and right (and up and down), and 1 of every 10 balls were chopping.

I also noticed my FPS on CO2 was 260 max and on HPA the best I could get was 170 FPS.

I'm leary about buying another A-5. Should there be that big of a difference between CO2 and HPA in terms of velocity?

if your doin milsim, get the new milsim tippmann

The problem was most likely the package you bought.

The stocks that come with the Stealth package are CRAP. Mine broke first scenario game I went to. Also, it makes the drive pen and spring sit further back causing you to have low velocity issues.

And then there is the Flatline. The Flatline will easily cause you to have curved shots if not correctly adjusted and it will also lead to many ball breaks due to it's "hard on paint" design.

CO2 and HPA shouldn't make too big of a difference but CO2 will generally give you a little bit higher velocity due to it's nature. However, you should easily be able to reach the legal 300fps with HPA, it'll just take more gas to do that.

My suggestion, if you still want to stick with the A-5 is to buy the A-5 stock. Then, add on what you think it needs. Want a remote? Try one. A new barrel, get that. Just play with the stock A-5 for a bit and if you need anything, then you can add those things on as you go.

If you want to keep away from the A-5 though, and have access to HPA, then I suggest an ICD Promaster. Or, if you want to keep with the mech route, check out Palmer's Blazer.

Good luck!

Thanks. I really do like what I see in the A-5 so I think I will get the base package and build on as you suggest.

Very well put Marmaduke, I agree totally. Alot of people are getting upped A5s now first without any experience with the A5. Each upgrade that you do could possibly hamper the performance of your marker. I myself do one upgrade at a time, install it then test it out. It takes longer but when you run into a case like BMan's above, then you need to get back to stock to find out what a problem is sometimes.

The A5 stealth is top of the line and comes with all the best upgrades Tippmann can offer in a stock package.

I for one have an A5 Stealth. IT's working okay and fine with shots going straight and a dead accurate.

The only slight problem would the velocity not going up higher than 265 fps.

I still love my Stealth but I may want to give it away

A flatline performs at it's best at that fps...a between 260-275 or so, any faster and you'll only get wil curve shots.

I know.

But I'm saying just so that it's only a slight problem.

I had a CAR stock on my 98C that caused low fps too...I got a maddmann spring kit to solve it, but I've read that putting a BB in followed by the drive pin and spring will help (no actuall experience with this).

I agree w/ Marmaduke. Buy a base model and put on the accessories that u like. No sense in paying someone to upgrade your marker to your liking. There a pieces in the kit that you may not like. This way you can build it as you go. There also may be things that do not work as good as others. I have about $400-500 ea. in the way I have both of mine and they are built to my liking not somebody elses. I myself do not like the flatline because of it being so picky about paint. I have an apex and a J&J. Search through the forums and you will find a lot of good info to help you choose the right accessories for you. What I like, you may not. A lot of the internal mods (polishing and trigger work) are good for everybody. Barrels,scopes, mounts, rails, and other stuff will be to you liking.
