ICS hop up issue

[Frostpirate]

Ok so my hop up will not apply hop at all, even when max I get nothing. I have a modify hard flat hop nub/bucking installed. It does feed fine just no hop. So ya any help would be awesome.

Hop ups are pretty much go/no go things. You may have to take the gun apart again, but not all the way. Before I reinstall a barrel/hop up assembly, I adjust the hop and look through the hop up to make sure that the nub is actually doing it's thing through the hop window in the barrel.

It could be that when you put it back together the nub fell out of place and now when the arm goes down it isn't doing anything. Unfortunately it sounds like you'll be tearing it down again. Did you do the mod yourself, or was it done by someone else?

It's the modify one, it comes with the nub and bucking u just install it, also I did look first and turned the dial full on and nothing.

Something went south in your install. Which ICS rifle is that for? If it's for an M4, is this of any benefit to you?

I dunno whats up, I tried it 3 times. The last time I made sure.

Make sure the adjuster arm is actually moving up and down.
If it moves, but you never see the hop actually come down into the barrel, then either your nub is not there, or you need a taller nub. Most people shim them up if they're not tall enough.
