Great pump for my bullboss - Hatsan TactAir Spark Portable PCP Compressor

I ordered this pump so id have mobility on filling my tanks , takes a minute to a minute and a half to fill my 230 tank , its almost maintenance free , id pull it apart and clean it every 6 months do to the carbon rings that wear , but you wont have to add oil like sum , i figure if it last a year or longer its paid for itself , so if your short on cash and want a decent pump for the price id definitely recommend this
