OK, so I just received my thread adapter and my k-var compensator in the mail today, and was excited to put them on my rifle. First, I screwed the adapter on my barrel, and it fit perfectly and felt rock-solid. BUT, when I tried screwing the compensator onto the adapter, it went on smooth for about one turn, then just tightened up and and I couldn't turn it anymore! I also tried the other side of the adapter and same thing happened. Any reason for this other than wrong type of threads? According to the websites, they are both 24x1.5mm right-hand threads.
Heres the compensator: My link
