Yes I have two, here's how it looks on the stalking rifle. They weigh in at 14oz but are really well built and won't wear out or rust like a lot of others, I have had one powder coated black with the proper high temp paint to match a blued barrel. Aluminium mods are lighter, but not as robust. The internal baffles, unless made of something like stainless steel, can be prone to gas cutting also.
The heavier jet z compact is an excellent moderator also.
