Hop up problem

[auzzie]

ThiS is really annoying. On my SCAR, the hop up knob (the type with the large knob on the back, not the 3 small ones on the side) falls off when I'm adjusting the hop up a lot thus I need to take apart the gun which is very annoying in the field. Is there a way I can keep that knob on? Maybe an o ring or washer Inbetween the hop up and gearbox

Does it look like the ICS M4 hopup?

I'm assuming it's a DBOYS/Echo1/CA? IIRC, the adjustable knob should "lock" in, by that I mean the knob should not be able to come off unless it's at a specific spot. Use this image for reference to understand what I'm talking about.

Sounds like the little stoppers might be worn out or broken? By stoppers I mean them little things that stick out, to hold the wheel on.

If the wheel keeps popping off, take the inner barrel and hopup out and look close to see whats going on. Might could fix it with a hot soldering iron. I would slightly heat the stoppers and make them stick out like they should. Sounds like an easy fix if your crafty at all.

If not, someone on here may offer to try.

After you take the hopup and inner barrel out, take a pic or two of the back end of the hop unit. "the part that goes against the gearbox" I would take one pic with the wheel on, and another with the wheel off.

If you want, I can see what I can do with it. I'm a pretty crafty guy. No charge, just cover shipping both ways.

I have excellent feedback, and I'm a mod on the sniper forums so you can trust me bro.. I'm sure others on here would agree, I wouldn't screw ya over.

I'm gonna be moving to Cali in a few weeks though, so if you want me to check it out, we should do this soon. Otherwise I wont be available for an unknown amount of time due to the move etc..
