The Eagle Vision Sigma M41 takes the proven Sigma modular suppression system to the next level with a substantially larger 41mm high-volume expansion chamber designed specifically for high-output PCP air rifles. Built for shooters who demand serious suppression performance without sacrificing modularity, the M41 combines exceptional sound reduction with Eagle Vision’s industry-leading interchangeable liner technology.
Unlike conventional “universal bore” moderators that compromise efficiency and accuracy, the Sigma M41 uses caliber-specific interchangeable internal liners that can be swapped in seconds without opening the suppressor body. This allows the internal bore to remain properly matched to the projectile, improving airflow control, reducing turbulence, and maximizing suppression performance across multiple calibers and rifle platforms.
Precision CNC-machined to tolerances as tight as +/- 0.02mm, the M41 utilizes a sophisticated dual-tube architecture wrapped in ballistic fiber felt and stainless steel mesh to efficiently dissipate high-pressure muzzle air. The larger 41mm diameter provides significantly greater internal volume than slimmer suppressors, making the M41 exceptionally effective on powerful hunting and long-range PCP rifles where smaller moderators begin to struggle.
Despite its increased suppression capability, the M41 maintains excellent balance and handling characteristics while offering unmatched flexibility for shooters running multiple rifles and calibers.
