Heavy doesn’t correlate with quiet. Sometimes to durability depending on what you want to do with it. Either way I’m sure that you’ll enjoy them. You can’t beat $350. I have a Mask and love it.
This one takes a 308 down to 131db. Comparing it to others on the market, that was the best I found. At 25 ounces, it's far from the lightest, but there are a lot of heavier mufflers on the market. It won't see heavy use. I figured at the $350 price point, I couldn't go too wrong. I am confident that the money spent on the Mask was money well spent.
