Hey guys,

my ICS M4 is having some issues with hop-up. It started out of the blue during a game a couple of weeks ago. When I shoot, the bb's look like they have "reverse" hop-hop...the sink like crazy...even with the hop-up on max and completely off.

I have replaced the hop-up rubber and complete hop-up assembly with brand new ones (from ICS). I also replaced the inner barrel with a new ICS inner barrel. Still nothing....bb's do the same thing no matter how much I turn on the hop-up. Everything was installed properly.

I made sure the inner barrel is not wobbling anywhere and that it is nice and snug inside the outer barrel (thought maybe it wobbled a bit and would bounce the bb around before it left the berrel) but still nothing.

I looked at my loading nozzle and upper gear box and they look fine.....

This gun would always shoot super straight....

Does anyone have any ideas what the problem could be??
