Should I let the air out?

[Coral Sniper]

Hey guys,

I had recently ordered a mamba but the mail service would not allow it in the U.S.

So I bought a cyrano110 instead and will get a mamba kit later.

My question is I have some friends of mine that will be bringing the gun with them to Tonga, The gun is brand new and was shipped directly to them. Should they release the pressure out of the gun before they fly or will the gun be okay? If they do have to let the pressure out, do you think they could do it having never seen a pnumatic before? The reason I am asking is because I have never used a pnumatic before. Any advice would be appreciated.

yeah as long as its in with the luggage down below it should be fine i order mine from spain/usa and havent had any damage to any of my guns with the air still being inside them while transported through air delivery

'Pressure containers' are a restricted article according to most airline regulations. For airtravel I always let the air out.

Cheers, ulysses

As a side note,I have a few pneumatic guns and I don't get to use them much. I don't store them fully pressurized. I let out all the air, and then, I pump several strokes back into the chamber, just enough to push the piston firmly back to the muzzel stopper. There is no sense in retaining massive amounts of pressure on the 'O' rings. And it is really important to keep the inside of the barrel lubricated with oil. Cheers

I recently ordered a Cressi from the USA. Had it shipped to my mum's house in the states and then she brought it out to me in Australia during her recent visit. I was advised by most, to remove the pressure before flying. It was pretty easy to talk my 63 year old mum through the process over the phone. Your mates shouldn't have any trouble.

Yep, it would be highly irresponsible (and illegal) to air ship a charged pneumatic.

At 30bar, if the gun fails it could cause critical damage to the aircraft.

That's good advice and what i do, about 30/40 psi is a good storage pressure, you need a certain amount of pressure to hold O-rings in shape they will deform with no pressure.

Also, keep pneumatics away from heat/out of the sun, the O-rings can be sufficiently softened that when you fire they can become unseated and you'll have rapid air loss!

Sad thing is I dont even know the process,closest I have ever got to a pnumatic was holding one in a store.

This is what I know correct me if I am wrong.

1 you set the gun muzzle down handle up for 30 minutes.(so the oil drains down)

2 unscrew the plastic cap at the back.

3 (I have no idea what this looks like) I am guessing it is like a tire and you push a little pin down and air shoots out?

and its done then right?

Yep, that is correct.
Make sure the implement you use to depress the pin is slightly rounded, don't use a 'sharp' needle or anything as this can scratch the valve.

Pretty much, but your mate will want to wrap a cloth around the tool used to push the valve stem, just to catch any oil that does spray out. Also, the valve stem is kind of hidden down in the little centre hole. My mum got a bit confused because she couldn't see it poking up. Just use a blunt tool or roll pin, etc. about 2mm diameter and push right in the middle of the valve and the air will come out.
