Suppressor soft jaws

[JF0]

I had this same experience trying to get a keymo adapter off a new sandman x. Ended putting the suppressor and one wrench on the floor and had to stand on the other wrench. With a little bit of bounce it broke loose.

Held mine and used the impact wrench. As thin horn said, came right off. I'd tried everything. Worked like a charm.
