I pull trigger and does not re-cock, just hiss

[epl]

I had issues with the gun auto firing. Now I fixed the issure. After 2 weeks of not using it, I shot it for the first time today. I pulled the trigger and it shot once and then it just hissed.
I have checked the level 10 and I have the lowest shim. Can anyone help

Tune your bolt... use the guide in the tech forum to tune it propely and after you get the correct spring and carrier/o-ring combo it will hopefully be fixed

If not then fill us in on what you did to fix the full auto problem because there could be a problem with your pin

you valve thumb screw might be too tight or too loose aswell.

I replaced the x-valve seatign o-ring. I gased up once more and now the gun auto fires again. I just bought the gun and it keeps messing up on me. Im starting to not be happy with the gun.

ULT? is the trigger rod set to the right length?(paper thin better it and the back of trigger on gas up)

Sear's condition? bolt condition?

well... hmmm im not 100% sure what to tell you, only thing i can say is that you might have to send it to someone to have it looked at. i know there are tons of people willing to help.

other than sending it to someone here are the only other things it could really be (check/try them in this order if possible)





~ crank the velocity and throw in the gold spring and try again (turn the back to the right to turn it up)

~ make sure its a hp tank and not a lp tank

~ try a different ASA/tank Combo... sometimes its just a bad mix which gets bad airflow

-----------------------------------------------------------------------------------------
do all of the next ones before gassing it up again
-----------------------------------------------------------------------------------------

~ send me/us a picture of the sear tip and bolt lip ([email protected])

~ check the o-ring that you replaced for any damage (if need be, replace from homedepot or a similar hardware store)

~check the rod length when gassed up

~ tune the bolt carrier and o-ring combo

~ tune the ULT





other than that no ideas... but let us know, and i am sure one of us on here will be more than willing to help you out to the best of our abilities if you sent us the marker. (ruler does a great job tuning mags) and i know tuna is awesome but he is always loaded so turn around time is kinda slow

Most important thing before you start to take it apart, Is it running on High Pressure Tank?
Low Pressure most common cause for auto firing. In fact I just worked on Tac One with that same problem yesterday at local shop.
