The A-5 is one of the most modifiable paintball markers in existence. Some products are performance upgrades, while others are purely aesthetic. Kits available at many stores and websites can allow the A-5 to resemble many real-world firearms
Some of the many upgrades include:
Tippmann A5 Barrels
Tippmann A5 Body Kits
Tippmann A5 Camouflage Kits
Tippmann A5 Compressed Air Low-Pressure Kits
Tippmann A5 Drop Forwards
Tippmann A5 Electronic Upgrades
Tippmann A5 Expansion Chambers
Tippmann A5 Foregrips/False Magazines
Tippmann A5 Hoppers (due to the unique Cyclone-Feed System, very few hoppers [the stock hopper, Ricochet hopper, TAC-Cap loader, and a 240 round ammo box version] are available).
Tippmann A5 Tactical Shrouds
Tippmann A5 Triggers
The upgrades available from Tippmann specifically for the A-5 include the CAR Stock, Response Trigger, E-Grip, Low-Pressure Kit, Expansion Chamber, Universal Mount, 98 to A-5 Barrel Adaptor, Remote Line, Sniper Barrel (12", 14", 16" lengths), Camouflage Graphics Kit, Double Trigger Kit and Flatline Barrel System.
