Here is another way to fix the hop up unit from moving around in the outer barrel. i borrowed this idea from netpoc from the KWA Forums. i actually really like this way better then my original idea and i will give credit where its due..unlike some other folks here on Youtube.
doing this oring mod to the inner barrel behind the hop up unit is very similar to WA/G&P hop up unit that holds the adjustment wheel in place from sliding off.
dremel at your own risk. as you can see in my vid a small shallow groove is all that is needed. go too much and well..i guess youll be buying another barrel..just dont blame me for it.
