I will make more as soon as I can. This is a direct replacement for your Air Venturi Avenger OE barrel and shroud. A more free-flowing port has been machined into the liner adapter that fits in place of your barrel. The liner is held in place with compressed orings, much the same way FX uses.
The liner adapter and air stripper are threaded, and the carbon liner screws on to them. Rubber cebtralizers / vibration dampers keep the liner straight and bad harmonics down.
You are able to swap in any of the other the 700 mm pellet liners, should you want to change the twist rate. Thank you for looking at my listings.
