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 

Weight: 300g 

Length: 247mm 

Length covering the barrel: 170mm 

Silencer extension length: 77mm 

Barrel diameter: up to 15.20mm
