Difference between tippman a5 and tippman a5 stealth?

The Tippmann A-5 is popular partly because of it's H&K MP5 styling and easy to modify design. It therefore attracts many players and companies who wish to take that mil-sim look to the next level. There are now plenty of variants which add stocks, grips, clips, shrouds, sights, scopes and other mods that take the A-5 into any infinite number of military appearance configurations. One of these is the A-5 Stealth package. This gun is mechanically identical to the standard A-5 but adds:

Flatline Barrel- This barrel has a curved inner tube that gives the paintball backspin to reduce it's "drop" in flight and increase distance. It's important to know that this barrel has a reputation for being finicky and generally requires the use of premium paint (the curved tube spins the ball by using a coating of ultra fine sand which can shred cheap paint). It can work well if you take the time to adjust it, clean it and use good paint.

Off Gun Air Line: Air tube that goes to a tank on your back, lightening up the gun

Collapsible Stock: With the tank off the marker a stock helps balance the gun

It's worth noting that all these mods and more can very easily be added to a standard A-5 at any time, so you can pick and choose as you go if you prefer.
