It is kind of hit or miss with every G6 I have played with. My buddy Caylen's won't last more than two days play before he is resetting both regs; and each time it has been caused by the screws vibrating loose from shooting. Like I said, we're well aware of blue loctite, but the entire issue could be avoided in a cleaner more consistant fix by just adding an oring.
Schrader is good, happened as much at 5 cases as it does at 50+ cases now, and on a couple different guns.
It's a hit or miss issue. Kind of like the battery issue with the 2011 G6R's. My friends and I all have G6R's and two if us have no issues. The third has an LPR that backs out. Loctite is the easy answer but there's probably a longer term solution too.
