I bought a maverick as my first pump marker. Imagine my surprise when I read that mavericks aren't supposed to be able to cock unless their pressurized. Right now it cocks just as easily as it does when it's gassed up.

Also, my velocity is all over the map, and I can't get it above 260, with low shots around the 190s, a 70fps difference!

Which leads me to believe: is it the springs? I'm sure after a lot of use the springs wear out. I think the velocity and cock-ability are caused by weak springs. Any gurus know about this?

Thanks for any help.

I had the same problem. What my problem was that the balls were rolling out cause the detent spring was burried. If this is your case, then the only way that I found to fix it was to get Phantom sizer rings. Once I put the red one in, I have no problems. Cost me $7. The next thing that I want to have done is put a bottom line on it and also mill holes in the barrell. THE THING IS SUPER LOUD!!!

that spring in the barrel isnt for holding the ball in place after loading the ball into the barrel, it's there to stop double feeding. That's why the bolt covers it up when the pump is pulled forward.

I use marbalizer paint in my maverick and the balls don't roll out as often, but i still get 1 or 2 every 20 times or so.

Also, j&j makes a ceramic barrel for the maverick, if i can i'll post a site to buy one, it def. makes my gun alot quieter.

You'll need a phantom grip to put a bottom line on it or you can try and find a euro grip bottom line adapter

Haha no guys. Thanks for the help but I'm talking about the main spring and valve springs.

Yes, when I first bought my Maverick, the velocity is off the chart too. I went and bought a nelson spring kit. I have the very stiff spring on mines right now.

Any gun is able to cock even when they are not pressurized. You can cock it back because of the spring pressure. If you put the stiffer spring in there, it will be a little harder (as in tension) to pull the pump back.

Thanks zz rai I'll do that.

By the way, that's a very cool vsc mod. How'd you do it?

Phantom parts. The trigger guard was the hardest part. I broke my trigger guard so I had to make a new one. The pictures there are old, I've actually put in the compression hardline, took out the x-chamber, and put a new aluminum trigger guard on my gun. I'll get some pictures up some other time.

[MrSandwich]

Did you glue the co2 changer onto the guard or does it just fit?

[zz rai]

I drilled it. But for the new trigger guard, I drilled it, screwed it, and epoxy'ed it. LOL. Hopefully, the new aluminum trigger guard can withstand the pressure of the VA adapter. But to answer your question, I drilled holes in the trigger guard and used the screws that came with the kit to attach them all together.

Rather than spend money on the Phantom breech rings, you could just do what everyone did back in the 80's- put a strip of electical tape inside the barrel to stop roll-outs. For extra fun make sure the strip is oriented along the top of the barrel for an amazing flatline effect!

Yes, I'm kidding.

And zz, I've never handled a Nelson gun that could be cocked when it's degassed. On my Maverick I know, the spring pressure behind the valve is not enough to push the catch forward enough to let the hammer catch. My friend's Phantom is the same way.
This may be the root of the problem- if sandwich's valve spring is too heavy it would explain the low velocity too.
