You need to make an intro post in the introduction section. Forum rules.
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
Just got a new nozzel and it is still crap
No compression have tryed teflon tape and nothing
Have a l96 pdi hop
Mad bull 6.03 barrel
Guardder h bucking
Any advice would help so much as its sending me mad
Sorry new to all this how do i go about that ?You need to make an intro post in the introduction section. Forum rules.
Yer i have 100% compression on the piston but not at the hop upFirst 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.
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.
Yer both o rings are good checked and recheckedDid 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?
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. 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.
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 !
Any ideas what size the oring is as i might be able to get one from some where without buying the hole kit. !
sorryWait, 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?
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.
