Part 3a: Leak Guide
Got a leak? I've got a fix.
Symptom: Leaking from breech/leaking down the barrel
Solution: Check (and/or replace) the rear feedneck oring (017) as well as the front bolt guide oring (013)
Symptom: Leaking from the frame
Solution: Make sure you are using a Low Pressure tank, then check (and/or replace) the two orings that sit between the frame and the body, just behind the trigger (1x3?)
Symptom: Leaking from vent port
Solution: Check the bolt sail oring (016), rear bolt guide oring (013), the external can oring (stretched 017) as well as the first oring behind the can (first oring of the four, closest to the threads. should be an 017) . I also recommend making sure the transfer ports on either side of the FT screw have NOT been touched and are sealed properly with teflon tape and/or a spec of blue threadlock
