SIGMA M4 Suppressor

The Sigma M4 airgun suppressor is made with the highest standards in England. After years of testing, Eagle Vision developed an airgun suppressor that not only quiets the gun but is also designed to reduce barrel vibration through a series of polymer bushings that create a rigid core and dampen vibration. Many airgun silencers are produced en masse, with cost-cutting as their primary concern; the Sigma is manufactured by a 5 axis CNC, and internal parts have tolerance to + or – 0.02. At first look, it is evident that the Sigma M4 is not just a knock-off of an inexpensive 22 LR baffle core, but a quality product looking to push the boundaries of airgun silencers.
