Hi friends, I have this: And I want this!: I dont know if having a compensator attached to the outer barrel will cause issues. Should I buy it?

Hi, well, i talk about this in the other thread of the compensator for a glock, But I really don't understand how it work the compensator inner threaded outer barrel with the thread adapter and the compensator, for example, when the adapter is a 11mm CW and the 14mm CCW, what the hell that it...

Hi guys I have this upgrade in mind, I want to extend the inner barrel of my glock17 and I need to hide the barrel with the compensator, But which one is the best option, the one is attached to the lower raíl?, or the one is attached directly to the outer barrel?
