The Sumatra 2500 500cc is very popular due to the air volume and power balance. The shooter can tailor the velocity output according to the target size with the power adjustment wheel. The 500cc models give between 40 and 60 accurate shots depending on the power setting before an air top-up is needed. These rifles do need silencers if the sound is an issue for the shooter.
 
Please note that the following is required for this rifle:
- 1/8" Female Standard Series Male Nipple
- 1/8 BSP Dowty Washer
