Sound Moderator SIGMA M4

A multi-caliber sound suppression system that can be used in various air rifles of different calibers. The interchangeable internal insert can be swapped for an insert of a different caliber without opening the moderator using the provided tools.

No moving parts, all components are secured with O-rings to improve accuracy, reduce vibrations, and prevent pellet clipping. All parts are CNC manufactured; Some internal parts have a tolerance of + or - 0.02. All inserts can be used with future models of Eagle Vision sound moderators. Caliber-specific lining reduces noise levels to a minimum.

Additional ventilation holes on the first tube release air pressure from the first to the second chamber. The space between the first and second tubes is pre-wrapped with ballistic fiber felt to reduce sound leakage - it is also wrapped with stainless steel wire mesh for a stunning appearance. The external groove is designed to release air and provide a better grip. Also with interchangeable end cap.

Available linear calibers: .177, .22, .25.

Can be used with various calibers up to 10mm after removing the insert.
