Spring guide stuck inside piston
 

Hey guys, i have an echo1 p90 and i had just installed a m95 spring inside the gear box after checking to see if everything was aligned I closed it up and took a couple shots. after 2 or 3 shots it had stopped firing and a horrible grinding sound took its place. i opened it back up to check if it was the gears how ever i noticed that the piston was in the back of the gear box and the spring guide wouldn't come out of the piston.

any help would be great
Thanks

i finally got the spring guide out reassembled everything and tried firing again same problems persisted so i took everything apart and switched the piston for a stock one fires fine but it shoots very softly. being shot about 10 feet away only a little pain is felt like a hard flick. is this how an m95 shoots or is something wrong with my piston now?

I've had this issue in the field with a guy's M4. Point the end with the spring and guide away from yourself... it's like a bomb right now. Hold the piston and tap it on the table or something hard. The spring and guide will shoot out when freed.

Putting it back together look at the spring guide to ensure it's together... if it has bearings or a screw in the end, it might have come loose and caused your jam. If you don't have bearings on it, change it for an other as it is too big to accommodate the compressed spring inside your piston.

Alright thanks ill try that

alright so i've hit this piston on floor countless times it still hasn't come out any ideas?

The only way to safely remove it is to sacrifice the piston. Use a Dremel and cut the piston at the end, it will open up and the guide and the spring will come out.

If there's a screw in the end to take the bearing off the guide you can remove that and it all should fall out.

Be careful though, as I said, it's like a dynamite stick waiting to go off.

Personally, I would just scrap the set and get a new spring, spring guide and piston.
