Any gun will have problems if you don't maintain it properly and use the recommended lubricants. Bob recommends Dow 55 because it makes the o-rings swell and seal so much better than Dow33. I'd be willing to bet all the guys who reviewed the marker were using 33. 33 will do the job, but you will have problems eventually. So use the correct lubricant and you will be problem free. Making sure all of your o-rings are intact are probably the biggest cause of leaks. If you change your o-rings out on a schedule and clean/lube everything when you do, your Marq will be the best shooting, most reliable gun on the field. You gotta put love into your Marq before it can give it back.
I went through and read all of the reviews here on pbnation about the Marq6,7,Rapper and every one but one guy knocked reliability down a notch or two only because they said Maintenance was a pain. The one guy who knocked it for issues out of the box said the problems were fixed with a few simple procedures and it shoots great now. Maintenance affects reliability only if you don't do one, obviously it becomes less and less of the other.
