[Eagle Vision] SIGMA-M51 Sound Moderator + Calibre Adaptors

Description:

The EVC Sigma-51 silencer is a high-quality airgun sound moderator designed primarily for air rifles, offering effective noise reduction while maintaining accuracy.

Manufactured by Eagle Vision, it stands out for its modular design that allows users to adapt it to various calibers without disassembling the entire unit. This suppressor helps minimize the sound report from airgun shots, making it ideal for hunting, target shooting, or backyard plinking where discretion is preferred. Its robust construction ensures durability and reliability, appealing to both novice and experienced airgun enthusiasts.

Key features include an interchangeable internal liner system secured by O-rings, which eliminates moving parts to reduce vibration and prevent pellet clipping.

The unit measures 187mm in length with a 51mm diameter and weighs approximately 266g, crafted from anodized black aluminum for the main body and liners, with stainless steel air stripper adapters. It incorporates ballistic fiber felt between tubes to further dampen noise, and all components are CNC-machined to tight tolerances for precision.

The design supports easy caliber changes using provided tools, enhancing its versatility.

Compatibility extends to multiple air rifles with calibers such as .177, .22, .25, .30, and up to 9mm when used without a liner. It comes with various end adapters like 1/2 UNF, M14x1.25, M18, and M20 for broad firearm threading options. The package includes liners for common calibers, spare O-rings, grease, tools, a waterproof storage case, and a protective pouch, ensuring users have everything needed for setup and maintenance. Future Eagle Vision models will maintain compatibility with these liners and adapters.
