Question: Can anyone explain to me why there are two sleeves? how does the second sleeve come into play?
Document: It does exactly what it's designed for. The blast is reduced greatly for the shooter. I would buy again for other rifles.
I really like this for guns where the forearm comes right up to the end of the muzzle break. It is longer than any of my other breaks but it is MUCH quieter. I took it off my 11.5 in AR since it added too much weight and length to the barrel.
Answer: no
