This is an excellent upgrade option for your CoolFire Trainer System:
Screws into the end of the CoolFire barrel after installation into the slide.
For best results fill extenders with a 20 oz or other large paintball CO2 bottle or with a 14 oz sodamaker CO2 bottle.Conversely, we don't recommend filling from 90 gram pre-filled cartridges, or with 3 oz sodamaker bottles.
Each unit includes (1) Care kit.
