Thanks guys. It didn't seem right to have to cut it. The youtube video method was like performing surgery on the forend.
I unthreaded the nut half way, pushed on it and that go it loose. The Hogue was much easier to slide together. In no time I had it back together. I liked the feel and grip on the Hogue but it seemed to have a lot more play than the Mossberg piece. I was also getting a metal on metal sound from it. I put the Mossberg forend back on, the sound went away and it did seem to have less slop. I swapped the Hogue back on, made sure everything was seated properly and it was the same. I put the Mossberg forend back on for now as the last thing I need in a home defense gun is it making an ill timed racket. Any ideas beside contacting Hogue?
On the plus side I can take the weapon down and put it back together faster and faster.
Thanks.
