SR25 double feed?

So, I encounterred a problem, that often the rifle double feeds after a few rounds. Any idea what is causing it? Ive changed and reapplied the hop up rubber and delayer, but it still double feeds and misaligns the hop up bucking and delayer, causing to have a very weak hop up effect.

EDIT: To clarify, I have the CYMA CM0.98 SR25

I havent modified the air nozzle, it is stock. I am planning to change it, for better compression.

After realigning the hop up rubber, yes, but then it double feeds after and then doesnt apply much hop.

Sorry not too sure. Maybe pull the bucking put and check the nub to see if it has been damaged.

Ive did check them and they look fine. Maybe I did a poor job on fitting the hop up unit, I will check more.

Also, couldnt this be caused by a shitty hi cap magazine?

What if the new hop up rubber would be causing the double feeds? I installed a Maple Leaf monster 80 degree rubbeer. Would that be an issue?

That most likely is the issue. Not sure why but put the old one back in.

Maple leaf aeg buckings have pretty loose lips and tend to be longer then most and occasionally need to be trimmed. Teflon tape can help if you are skilled with it. If you have a spare nozzle with an oring in it, pull the oring our and put it around the bucking lips. It should tighten it up enough.

Did you try mid-cap mags on your SR25?
I only use mid mags on my sr25 with no double feeds so far.
Never had feed issues with stock nozzle, ML MrHop bucking, or this nozzle in use

No, dont own any mid caps yet.

I was planning to replace the nozzle. Gonna test out the gun with stock hop up rubber.

I don't think the nozzle is the issue.
