Viper BackFlo 1/2 inch UNF Female Thread Airgun Silencer 247mm long fits 15.20mm barrel
Backflo technology takes the sound from the barrel into the suppressor and back down the outside of the barrel.
This Viper silencer utilises Backflo 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.
Backflo 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 15.20mm in diameter.
Suitable for .22, .20 and .177 calibre AIR RIFLES ONLY.
Length covering the barrel: 170mm
Silencer extension length: 77mm
Barrel diameter: up to 15.20mm
