that is a very good question actually. i would have to look at it. But, i would imagine it is to seal or prevent leaking. have you taken it out and aired it up to see what happens?
@@stuffwithdono I'm getting some air this week. Havent played paintball for 12 years or so and getting back into it. I vaguely remember it leaking occasionally from the rear. The groove on the back LOOKS like an O-ring belongs there but does not reflect it in the manual but you're right it seems like just what the gun needs
i just got it apart today and cleaned it and after i put it back together it shot great but then started a little leak, i did some research and im buying a o ring rebuild set for the g4 and im gonna replace all the o rings in the reg aside from that i have no idea what else it could be
Nicolas Hernandez well the differences of the bolt engines is that the bolt and the bolt guide stem are different sizes. but yes. supposed to be the same solution. just be sure you use a good thin lube.
+StuffwithDono yeah the elbow can move but if the line goes in bent it isn't going to seal the same as if it went in straight I had the fx and had the issue as well
No but I tried not to long ago. It always fixes just like you said but every time I turn the air on, it leaks. But that's the only troubles iv ever had with it lol its been amazing
if lines leak there is another fix. watch this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Xfx3GWaWuaw.html not trying to step on ur video just trying to help everyone. Also use lighter grease ( helps bolt stick ) or switch to tech-t bolt (as you said. just don't turn the bumper/dump valve around. It will shoot the O-ring out lol Good video. Thumbs up love helping ppl. hope this helps ur viewers mate
This is NOT how g4/g5 works as you explained!!! The bolt movement is about 22mm or 0.87inch, it never come that much forward as you demonstrate in minute 4:13 and that is also not causing the "boltstick". Once the solenoid release the air pressure in front of the bolt, the pressure behind and around the bolt, forces the bolt to move forward. The bolt is conical on the inside, that allows the air to escape and blow the paint trough the barrel and seal again once the bolt is in the back position. The bumper is also not a kind of a spring that send the bolt back, bolt movement is only initiated by the solenoid and different pressures in the front section of the bolt and behind. Just google for "dangerous power g4 + .gif" Bumper is just what is named, a bumper, to avoid metal on metal contact. BOLTSTICK for G4 and G5 is when you fire and the bolt needs longer then a split of a second (~1/35th) to return an clear the breach. Without a hoppper you can watch from above, how the bolt returns like in slow motion or just stuck on the half way. This is mostly caused due to the lack of grease on inside the body orings (dry orings). I suggest to lubricate all bolt touching orings (#2,#2,#3,#10) and place additionally a good amount of grease (dow33, GOGgr33se, DP40, ...) between oring #2 and #3 shown in the G4's parts diagram, this is how i get trouble free weekends of paintball recreation. If you have first shot drop off, activate ABS dwell and / or increase dwell settings. Breach wear?! If orings missing or you put dirt in the gun, this is only causing breach wear, it technically doesn't matter if a oring is riding on the bolt or if the bolt ride between orings.
