First test the compression inside the cylinder by firing the rifle with your finger on the cylinder head nozzle (to prevent air from escaping). The piston should either move forward very slowly or not at all if you don't remove your finger. If it slams forward, then you know there's a problem with the compression of your cylinder.Hi im having the same prob with my l96

Then, test the overall compression of the rifle by firing the gun with the cylinder head nozzle inside the hopup/barrel assembly to imitate the position the rifle makes while firing, cover the end of your barrel with your finger, and test compression again. The piston shouldn't be able to move forward/move forward quickly until you remove your finger.
If your rifle passes both these tests, and the issue persists, then it's probably because the cylinder head nozzle isn't going far enough into the hopup unit/barrel.
Sorry
Sorry new to all this how do i go about that ?You need to make an intro post in the introduction section. Forum rules.
My l96
Ive tried dental floss and teflon tape but still no joy

Try getting a new bucking then. Also, definitely check if your cylinder head is going far enough into the bucking.
Did you install the o-rings that came with your PDI chamber? There are 2 o-rings that you have to install, one at the front end and one at the rear end of the chamber.
Also, make sure your inner barrel is pushed all the way into the PDI chamber and is anchored by those 2 screws on the side.
Lastly, make sure your bucking isn't ripped. The PDI chamber can easily rip a bucking when you insert it into the chamber along with the inner barrel. I find it best to coat the bucking lightly in Vaseline or something similar before inserting it.
Lastly, what kind of cylinder head/nozzle did you end up getting?

And the screws sit in the grooves as for the nozzel it was from airsoft sniper parts uk

Do you think its the bucking ? Its fine no damage !
What one would you recomend ?
Ive have replaced the bucking with a mad bull shark and its no difference
Now i have run out of ideas
Any help would be welcome

Can you describe exactly what you are experiencing as a problem?
Like, there may be something else going on that makes you think there's no compression. For example, maybe your bb's aren't even feeding into the chamber, or maybe you have too much hop up and the bb's are "stuck" in the chamber. Just want to make sure that none of those are a reason.
Did you try it with your old cylinder head?

Right i have a 100% compression in the cylinder but when the cylinder is cocked and i perform the compression test with my finger over the barrel all the air comes out the hop up / nozzel end
I have new washed bucking, teflon tape and dental floss on the barrel
All my bbs are loading fine and shooting fine no jamming !

I would suggest you to buy a pdi repair kit. The oring that came with my chamber didnt provide enough compression. It was fine no damage at all, but the compression was shit. still dont know. However changing the o- rings helped though i dont know why.
Ill give it a try just have to find one for sale now !I would suggest you to buy a pdi repair kit. The oring that came with my chamber didnt provide enough compression.

Any ideas what size the oring is as i might be able to get one from some where without buying the hole kit. !
I saw a boneyard utg shadow ops for like 60 bucks on evike...

Sorry not sure what that is and im in the uk
Is it a hop up ?
Is it a hop up ?
Wait, so is your gun capable of shooting? Like, can it shoot bb's? Or does all the air leak out completely and you can't even shoot a bb?
Because I'm pretty sure it's just that you just aren't getting good compression where the nozzle meets the hop up chamber. Part of me doubts that ALL of the air is completely leaking out and you are getting absolutely no air behind the bb, because that's what it sounds like right now.
If that's the case, then the only places where the air can leak out is between the bucking & inner barrel, the inner barrel & hop up chamber, or the nozzle & hop up chamber/bucking.
Did you properly install that "silver ring" that came with the hop up chamber? You're supposed to wrap the bucking around it, slide it over the inner barrel, and then secure it onto the inner barrel.
What kind of inner barrel and bucking are you using?

Dont know the specs of the oring. Its good to have a repair kit just in case u loose 1 of the screws... Just buy it. Its cheap and always good to have 1 at hand. I loose things all the time. So i always buy a spare 1 when buying. If i find it needless i just sell it on ebay... But as for the compression goes. Try putting a cylinder nozzle in the hop up, plug the barrel and try to blow trough the nozzle. If its leaking try to find out where from. By listening where the air escapes. If its the chamber change all o-ringsIll give it a try just have to find one for sale now !

right i am able to fire bb's out to about 200 ft. but they tend to go up down left and right some short some a bit past
now i was told that it was my compression was not 100% and not consistant so i am trying to rectify this problem and get my l96 shooting like again im told it shoud.
i have 100% compression at the piston end, but when i cock my rifle and place my finger over the end of the barrel i get no compression just a loud pop
as for the silver ring the only one that came with the pdi l96 hop up is the one that slides into the barrel and then slides into the hop up to lock it in place
im using the madbull 6.03 black python ver II 509mm
and the madbull sharkfin bucking
yer i will buy one!! just wonderd what size they wher so i can get a load of thenDont know the specs of the oring. Its good to have a repair kit just in case u loose 1 of the screws... Just buy it.

plus i could do with a new spring as well
ok guys ive just taken the barrel and hop up out and placed the piston inside the hop up and blow down the barrel and no air escaped !!!!!
so i think i have been miss informed
but still not sure why it fails the compression test ?
i once had it where i would do the test and the piston would not slam untill i took my finger of the end of the barrel
but now the piston slams and only the smallest amount of air comes out the end of the barrel when i take my finger off
coulkd it be not enough volume of air in my piston
or am i just miss under standing every thing ive read ?:shrug:
