PB Sports

PB Sports services airsoft guns at its store in Fort Wayne, Indiana: it cleans and re-lubricates AEG gearboxes (they advise doing it regularly), sorts out guns that lock up, and advises on internal upgrades such as springs, gearboxes, barrels, motors and higher-voltage batteries. It fills nitrogen (HPA) tanks to 4,500 psi and CO2 tanks, and can send out-of-date tanks for hydrotesting.
