It's normal to have a low leak between a plastic nozzle and the cylinder outlet.

Usually the most difficult to troubleshoot leaks end up between the nozzle and hop up. They're typically caused by something that results in crummy fitment between the hopup body and the mechbox. Sometimes you just can't get a reliable fit between the hopup and the mechbox so the nozzle doesn't pop forward far enough to seal against the rubber sleeve in the HU.

If you are using a 1piece HU body, try hand loading pellets into the HU with the mag removed and chronying. With 1pc HUs, the magazine can pull the HU forward and open a gap in the nozzle-sleeve mate. TM really had it right with their 2pc HU design. It frees the upper HU to float against the mechbox and solidly mounts the bb inlet so a wiggly mag can't affect the barrel-HU-mechbox alignment.
