It's also the same size and isn't needed really. Doesn't seal anything and can be used as a PT oring in a pinch.

Can anyone tell me whats up with my chrono readings and how to fix it? Would the reg spring need to be replaced if its old or worn? Or is that not going to cause this problem?

This thing; is it even the reg spring or just the outside of it? And is it possible to install it backwards?

Edit; another symptom, if its relevant, is that the marker is "chuffing," kind of an RT effect except its not a full shot (doesnt chamber a ball) and sometimes the sear doesn't reset.

The inconsistent velocity readings definitely sound like some sort of regulator issue. I have never had luck with mags on CO2 even with expansion chambers, stabilizers, etc. As soon as any liquid gets in, all hell breaks loose. It could just be the reg seat not tolerating the cold and liquid. It could be a worn out spring pack. I suggest trying to get it working on HPA to rule out the effects of CO2.

This is what I was afraid of. I'll definately try, but I dont know how I'm going to convince my girlfriend to use a 13ci over 12 grams, or even 3.5oz. How many shots would a classic get off a 13 anyway (I'd test myslef but I'm outa town)?

Your only going to get 8 good shots off a 12g. Go with a 3oz or the 9oz. I run my mag pump off the a 3oz and get well over 150 shots.

Do you have the same liquid problems with the 3.5oz? Also, I was going to devolumize the shot chamber to get more out of the 12 gram, so if the problem isnt that I'm using a 12 gram ill stay with that setup. She really doesnt like tanks. Or hoppers.

This sounds like bolt stick. The bolt isn't returning all the way after a shot, which will give you a lower reading and not let the ball be chambered. After a shot take a squeegie and push on the bolt while watching the trigger. If the bolt pushes back and resets the trigger will move as well.

Ok, there's some seriously weird shi-tuf going on here. I got rid of the bolt stick by backing out the valve retaining screw, backed out the regulator adjustor and snuck it up on the 250 range, and started plinking.

Im getting 28 full velocity shots before it drops to sub 200 for two shots and dies. And I've done NOTHING to the internals, no seal forward o-rings or devolumization. I say full velocity hesitantly. It started off at 240-250 for five or so shots, jumps to 300+ for another fiveish, settles back into 280-290 for about ten, with the occasional 450fps winger. That happened about twice.

What the heck is going on here? I'd like to get this working this week, without killing anyone preferably.

Echo · 03-21-2012, 03:03 PM

Just tried again with HPA, and I had to adjust the reg before I tried a string of shots, since it was shooting about 150-170 without me having moved it from the 12 gram CO2 trials above. Once I got it up into the 280 range I tried a string of ten after having plinked for about 20 shots.

Lowest was 266 fps
Majority inside the 270 range
Highest was 288

Is there any way I can get this thing running safely on CO2? She doesn't like the weight of a tank, plus it looks ugly.

Ando · 03-21-2012, 06:54 PM

Well if you talked a little nicer to your mag, it might just work for ya.

How do you have your Co2 tank positioned? The preferred way to run a mag on Co2 is with a remote. If it's screwed on the marker with no anti-siphon tube. It's going to spike all over the place due to the Co2 getting into the valve.
