major air leakdown the barrel

[cgstrong2000]

Ijust bought a used automag rt and when I gased it up it had a major leak down the barrel and the bolt slowly moves forward. someone on the chat section told me to push the bolt back with a squigee. wich worked until I pull the triger.

when you gas it up hold the trigger. does it leak? if so then its the on off thats causing your leak.. check the orings on it.

Replace the powertube o-ring, and your bolt spring. Your bolt isn't locking back, most likely due to a worn out bolt spring.
