I chose this moderator not only because of the price, but also because of how
compact and light it is. I wasn’t expecting any miracles, so I was all the
more surprised by its noise reduction on my Kral arms puncher mega 5.5 mm. By
ear, I’d say about 40–50%. It’s like shooting from a Gamo arrow magnum
5.5 mm.
