Changing Hop up Bicking

J.D.R

Hey, just wondering if anyone knows where a good video guide is for changing the Hop up rubber in an M4?

I have a mad blue hop up, and a new barrel, but when I put the Rubber around the barrel, if wont fit back into the hop up housing. Is this just me, or is this a normal thing?

plenty silicone oil on the rubber should help it slide in easier and reduce the risk of tearing the rubber (giggity)

Sorted. I knew I forgot something. Thanks

i have the exact same problem and after half a can of silicone and an hour of frustration i gave up! any other suggestions?

I now we have the same gun, but it does work. It is frustrsting, but if you absolutely cover everything with the spray, and then do it slowly, it will work.

I can't remember exactly what I did, but I think I may have put the hop up in first, and then put in the barrel. Do it slowly, with a bit of a twist, and you will get there

Put the hop chamber on a hot radiator and it'll expand enough so that the hop rubber goes in.

And if it still doesn't fit, try shlapping on some more lube.
