The 98C is known for its relatively simple design, durability, and reliability, making it an appealing choice for newcomers to the sport. The 98C uses an iron-sight system commonly found on firearms. By depressing the front sight, the player can unhinge the feedneck, allowing for easy access to the firing chamber, thus allowing for fast in-game cleaning.
The 98 Custom can also be modified for speedball (Normally the 98 custom is used strictly for woodsball), using an e-bolt, which replaces the rear bolt with an air-powered ram, or, more commonly, an E-trigger which uses circuitry to trigger a solenoid which in turn trips the sear in set firing modes (the E-trigger is sometimes restricted on fields that require semi-auto fire only). When firing at high rates of fire (25+ BPS), apower loader is highly desirable for reliable feeding.
Another feature of the 98c is that by removing the six bolts on the left side of the marker you can dismantle the gun into two halves.
The marker is now being offered with Tippmann's anti-chop system, ACT (Anti-Chop Technology). "Chopping" is where a paintball is broken inside the marker due to parts inside of the marker chopping the ball. To prevent balls from chopping, the rod connection and the bolt floats slightly above the hammer in a long notch so if the bolt hits resistance, the bolt stops moving while the hammer continues cycling.
The Tippmann 98 Custom also has a large number of upgrades and accessories, ranging from aftermarket barrels to consistent regulators. The Flatline Barrel System adds extended range to the 98C by creating a backspin on the paintball. The Cyclone Feed System, found stock on the A-5 and X-7, uses excess gas from firing to cycle a spinning agitator to feed a paintball into the chamber after each shot.
