the ASA will only blow orings when you mess with the position of the asa. It is adjustable by loosening the set screws that hold it in place. If you adjust it to much to where the bleed hole gets blocked by a screw or the rail, it will blow orings when aired up or degassed. It was never a problem, just user error.
The g4 should only require you to lube the bolt once the night before you play. Youl want to make sure you lube it with a quality lube. I like the following greases
- lurker lube
- monkey poo
- violent pb jelly
- techt gun sav
- dye lube
Now, the g4 (when first released) had issues with the solinoid and bolt sticking. This is because the factory dp40 lube is GARBAGE.
the best thing you can do for your g4 when you first get it is to follow this thread
After a relube of the noid and regulator, the bolt will only have to be greased the night before you play. Thats it.
Servicing the bolt is doable in under 5 min. You just unscrew the backcap, slide out the bolt, wipe it clean and then apply new grease (dont go overboard, a thin layer is all you need)
Dump valve markers, by design, require the bolt to be lubed often because the grease does not stay on the bolt very long. I find that doing it the night before has always worked the best.
Also remember to unplug your battery when you are done playing, this will keep the battery lasting a little longer. A bad battery can cause the gun to shoot terrible. It should always be the first thing you check if you have problems.
