• Our multi-caliber sound moderator system can be used in different air rifles over various calibers.
• Interchangeable internal liner can be swapped with another caliber liner without opening the moderator with the tools provided.
• No moving parts, all components are secured with ‘O’ rings to improve accuracy, limit vibration and avoid pellet clipping.
• All parts are manufactured by CNC; Some internal parts have tolerance of + or – 0.02.
• All our liners can be used with future Eagle Vision sound moderator models.
• The caliber specific liner reduces the sound level to a minimum.
• Extra vent holes on the first tube release air pressure from the first to the second chamber.
• The space between the first and the second tube is pre-wrapped with ballistic fiber felt to reduce sound leaving – it’s also wrapped with stainless steel wired mesh to create a stunning look.
• The outer groove is designed to release air and give a better grip.
• Also with an interchangeable end cap.
• Available caliber liners: .177, .22, .25 use with out liner for 30 and 35 caliber.
