On the airgun market there is a countless range of moderators available. But finding one that really works, withstands long-term use and at the same time doesn’t strain your budget is not easy. That’s exactly why we decided to create our own brand called Black Rhino, which is specialised precisely in perfectly made sound moderators at a fair price. All our moderators are manufactured in the Czech Republic, directly in our own premises.
This moderator is designed for airguns in calibres 4,5mm, 5,5mm and 6,35mm and is installed on the standard external 1/2x20 UNF thread, which you will find on most modern airguns.
The Reaper uses a proven design with stainless steel mesh wrapped in felt, which effectively suppresses the sound of the shot. Everything is then protected by a robust carbon fibre tube finished with end caps made of aircraft-grade aluminium.

I chose the Rhino Short for my Walther RM8 because the silencer is very light
and still reduces the noise well. Since I also own the somewhat longer Black
Rhino, I noticed that the noise reduction is only slightly less with the
shorter one. Both are top quality and reasonably priced, as well as
looking good.

I compared it to one such evergreen that probably everyone knows, the Venox
moderator. The test rifle was a Reximex Lyra 4,5mm in 16J. The silencer is
almost 9 cm shorter, has only three baffles, but it silences quite well,
I estimate 70% of what the Venox silences. It's noticeably lighter. I tried
it on the Lyra because of the length, because without it the rifle is extremely
noisy and the Venox is quite long, where especially at competitions the length
sometimes got in the way. I was surprised by the accuracy. The sight picture is
better than the Venox and the biggest surprise was that after I took it off,
the shot didn't change. Where it flew with the moderator, it flew without it,
which was not the case with the Venox (there was about a 4 MOA difference at
30 yards). I should point out that everything is tied to the 16J rifle. With
larger calibers and power it may be different.
