Hello everybody! I was wondering if the piston can strip and what it looks like. I know that this is a noob question, but I am more used to AEG pistons. Thanks!

There really isn't much to strip... so to say. You can take a gouge out of the piston I would assume, that is if you are using your stock piston with a really heavy spring.

But they can't strip in the way an AEG piston would strip.

 

[silentfury214]

if it were to strip, would it cause any slam firing?

 

[vindicareassassin]

Is that a rhetorical question or a symptom of a problem you have?

The only real problem you'll encounter piston wise is like woogie said, you can gouge the holding lip, but if your issue is slam firing ie as soon as you pull the cocking handle back and it clicks into the sear but as soon as you return the bolt the sear releases again, that is generally caused by a knackered piston sear, but sometimes trigger sear and on occasions, both :-/ generally as a result of stock sears used with a ball achingly heavy spring

i have brand new polar star sears in the gun, and that is running all stock.

 

[woogie]

There is a possibility that you installed the sear wrong.... or have it adjusted improperly.

 

[silentfury214]

how could that have happened?

 

[zulu]

Generally when something is installed improperly, it's because...it was installed improperly!

I take it that you ARE having slam firing issues, then?

 

[silentfury214]

that would be correct zulu.

Take it apart again and make sure it all moves smoothly. Number 1 biggest mistake is not installing the trigger sear spring correctly, if at all, the wrong way round....... Before you completely dis assemble the trigger mech, make sure the trigger sear flicks back up real fast after you compress it if it doesn't return back up, or does it really slow, that will be your problem. Its the bigest cause of slam fireing/not cocking,using new sears, that I know of .

 

[silentfury214]

is there a way to get a new spring?

 

[vindicareassassin]

You took it apart, didn't take any notice it was there, and re assembled the trigger, and have now lost it..... havn't you? :

Not sure even where you would start to look for a new one :-/

You could try a supplier that stocks TM/BAR parts, or even a store selling car parts as they would have a selection of springs that might be the same/similar.

Alternativly you might want to put a WTB or WTT for some one who has swapped out their trigger for a Zero trigger etc.

i did not lose the spring, but the spring might not have enough tension to push the piston sear all the way up.

Check your not clamping the 2 halves together to tightly. You can make shims out of tin/cooking foil, place them between the body/washers/spacers of the body and test it again. Check you have the fixed end of the spring in the correct place or see if you can move it to somewhere where it will increase the spring tension, I dought there will be enough on the coil to wrap it round another turn.

Anything you can do to make the sear snap back up,and be strong enough to stay up and hold the piston, directly after release is good

Thanks Vindi!
P.S. doubt
