KJW 10/22 hop up not working.

[Rob121]

I am wondering if anybody else is having issues with their 10/22 hop up not working. I have reassembled the hop up a few times but it does not seem to be working at all. I was wondering if anybody has any hints or could help me out. When i put the hop up on and push the dial down just to check if everything is lined up properly I can see the rubber being pushed down. But when I fully assemble the gun It does not work at all.

I have this problem too.

First outing was fantastic and i was amazed at the length i was getting.

but after that the next 3 outings it to turn to crap, and seemed to become a sprayer at range.
still got some easy hits at 10 to 20m, but at range was just luck.

at first i put it down to leaving the hop-up on in storage, but storing it with the hop off didn't help ether.

i have just purchased a falcon enhanced rubber and will install it this weekend, although I'm unsure where i will get out again.
but i'm hoping the new hop rubber is the solution here.

oh i'm useing 0.3 bb's and green gas. and have custom inner barrel to original outer barrel length.
but other than that, internally i'm stock.

will try to update if i have any results.
