View Full Version : Bolt orings for 03 or 04 DX

03-20-2006, 01:34 PM
I have the old electra dx, I always use the same orings for everything in the gun because I bought 500 buna 90 duro tank orings on ebay for like $11.00 .It shoots fine but I have noticed that the bolt orings don't seal the chamber"I can see light past the bolt" Is this normal? The reason I use all the same orings is because of the oring chart on http://www.ottersccustoms.com/upkeep.html#oring "it says tank orings are the same size as everything else in the gun"

The reason I decided to ask Is because I bought some stuff to go lower pressure and I am stuck at 460 psi 290 fps. I didn't want to by an oring kit if I didn't have to because of having enough tank orings to last the gun forever.

Thanks for any info you may have for me!!

It's prolly just Kingman tolerences unless you got the wrong o-ring size. You might have to decide weather to go too loose or too tight. Where markers are concerned, too loose is better as long as it's not extremely loose. Your pressure concern may just be components and mods -

List what parts do you have on your gun. We can then help decide how you can get a lower pressure.
