If your RT Classic is like mine, those four rearmost 1/8"NPT ports on the rail are not connected via any passages to the banjo bolt.

I'm a bit jealous of your black body*. Mine's polished stainless, and not so good for woodsball.

Grivooga, lvl 7 or lvl 10?

For both, add oil. She may be dry.
If lvl 7, Move to a shorter power tube spacer.

You might also have a gummed up regulator piston. Clean and relube with grease (I think white lithium grease is proper, but can't recall atm).
It might be time for a new bolt spring. They do wear out.
Also check your bumper. If it gummed up with sticky crap, that could be it too.

It's a lvl 10 and it was oiled the previous week along with a thorough cleaning. Saturday is the first day of play that it's gotten with me. I have reason to believe that it's likely sat unused for several years though so it may be o-ring swell from sitting in the Florida heat for a few hours.

All the NPT ports on mine are through to the air passage. Atleast on the left side. I can't say anything about the right but I don't see why that would be different since there's a grub screw in the back of the rail on that side as well where the end of the passage was plugged in manufacturing. I can't think of a good reason why yours wouldn't be through to the passage. The passage is drilled from the back to the front and should hit every port along the way. It's not like it would save a manufacturing step unless they eliminated the longitudinal passage as well and took the forward most port directly to the banjo. Having only one set of functioning ports would eliminate the ability to move the front grip while retaining the hardline. Heck I like the hardline enough that I'm keeping it even though I'm not using it. I just plugged the bottom of the bike grip.

It's weird. I thought they'd all be connected as well, but the drilled passage stops at the middle one. Only the frontmost ports on the right and left side feed into the banjo bolt passage. I wish I knew why. I briefly considered drilling them through myself, but the little steel screws are rust-welded in place.

Maybe mine's a "Monday Morning" or "Friday Evening" gun... it would explain a lot.

I've owned two classic RT rails, I managed to unscrew those two little screws on one of them, on the other I failed. One of them didn't have the ports drilled through on one side, IIRC, but I think the other had all of them drilled through.

Also, I also hate how the trigger is limp when not aired up, and I'm Intelli-ing my mag almost solely for that reason.

Perhaps the rear screw moved some during play. Ive seen it with some mags that if the screws arent snugged right that it can cause bolt jams and such.

Just wanted to toss that idea out there.

Hmm, I doubt it but I'll certainly keep any eye out for less than snug screws as I break it down just in case.

my RT classic likes a really lose back screw, otherwise i sometimes get bolt stick.

like so loose the grip frame wobbles when its not aired up.

[Grivooga]

Hmm... I'm thinking of the geometry and the only way I could see that happening was if the sear wasn't clearing the bolt lip without that tiny bit of extra clearance. I'll have to look at it. My RT definitely leaks quite violently if the banjo isn't snug.

I just pulled my classic out...and she was having the same issue...
Swapped out barrels and shes firing fine again!! Some of my barrels are a little too tightly bored for my mags bolt...
I have always wanted a scuba tank...wonder if my field would let me fill it there...
