This Armex silencer utilises Back-Draft technology, which takes the sound from the barrel into the suppressor and back down the outside of the barrel. Utilising this method means that when this moderator is fitted the overall length of your air rifle does not increase dramatically as a large amount of the silencer fits down over the barrel.
Back-Draft moderators are extremely effective, even on spring powered guns.
This silencer has a 1/2" UNF female screw thread, but will not fit barrels larger than 16mm in diameter.
Suitable for .22, .20 and .177 calibre AIR RIFLES ONLY.
Length covering the barrel: 170mm
Silencer extension length: 77mm
Barrel diameter requirement:16mm
Piece of junk review by Rupert on 05/07/2018
Strap a baked bean can to your pcp and you will get a better result.
Open this moderator and you will find no baffles,nomuffling material in fact you will fin,d nothing! It is empty like a tin can. No sound suppression a total con. Massively dissappointed won't be buying again from r sunshines.
