A-5 Sputtering Issue, plz help!

I've seen a few post about this but I am having an issue where my A-5 will sputter as though it ran out of air while firing it and the cocking bolt will go forward.

It has an Etrigger on it, that is working correctly.
Ninja 4500psi tank.

Other noticed things that go along with it:

Issue will occur at random times with this tank and other tanks as well.
I've cleaned, checked o rings and re-oiled lightly all throughout the gun, no change.

This always occurs when firing multiple shots.

Ninja Tank will be much harder to get off when this starts to happen.
Sometimes taking the tank off and putting it back on it will stop for a time and I can keep playing.
If I stop firing before the bolt goes forward pressure seems to go back up enough to fire shots with long wait times in between.


Does anyone have an experience or suggestions to help?

Is your tank low pressure output? If it is, you need a high output regulator.

Also, check your bolt for wear where the sear catches.

It is not a low pressure. And a little background info on it, been in use for about a year.

And bolt has no wear or marks on it.

A worn or over lubricated sear or rear bolt will cause this. The sear fails to catch the rear bolt so it just keeps cycling. It doesn't take much wear either. Check the sear and make sure the edges are square and sharp. Same with where it rides on the rear bolt.

check regulator on your air tank. low on battery on your egrip. egrip might have problem if you took a part. to much oil. bad tombstone. bad valve. velicoty might be to high. if you are using a remote line something might be wrong with your remote line. bad bolt.

these are all the problem when i have that issue.

I've seen issues with this happening when a battery dies, and or the powertube/power valve is going bad, and need replacing

If you have a local proshop take it in to them, or if you do not, you can look in my sig, or also send it in to tippman

What type of egrip is in it? The old style or the new selector switch style? The solenoids are finicky on either model and if it starts to go bad that is one of the symptoms...try a new fresh Duracell battery...that is the only battery that my egrips liked...and what Tippmann recommends.

I posted about this happening to me,

To narrow down the issue I put the stock grip on it and it worked fine. So I knew at that point it was my egrip.

I didn't even notice, but the magnet that pulls the solenoid back had come loose and was in between the plate of the solenoid. So the sear wasn't able to catch.

I have cleaned it, I have had it cleaned by a buddy who runs a paintshop. Seems to have stopped....only happening once recently at GBG.

But I'm going to look into the solenoid, its the new model that has been changed to 13/bs from the original higher amount.

Thanks jdylnnn for that suggestion

Doubt its a solenoid. If that were the case it would click, not sputter.
