J.Bennett Omega Valve Mod 1 Tunable Gas Valve for Sig MCX 5.56/7.62x39

J.Bennett Designs Omega Valve Mod 1 Tunable Gas Valve (Suppressor Optimized)

For Sig Sauer MCX 5.56 (optimized) and 7.62x39 (works when suppressed).

Key Features

• 4 gas positions using the gas valve retaining pin for a wider adjustment range than the original two-position design
• Extended gas flow paths to delay gas entry and slow cycling for softer recoil and reduced mechanical stress
• Uses Parker Mountain Machine SCAR gas jet screws to vent excess gas out the front for precise tuning
• DMLS additive manufacturing from 17-4 stainless steel
• Hexagonal Boron Nitride (HBN) coating for extreme lubricity, temperature resistance, and reduced carbon buildup

Compatibility

• Compatible with MCX Virtus, MCX Spear LT, and MCX Rattler LT in 5.56
• Works with 7.62x39 barrels when suppressed (optimized for 5.56 valve settings)
• Some late-production Legacy MCX may be compatible (earlier Gen 1 Legacy MCX require the Legacy-specific Omega Valve)
• Not compatible with 5.5" 5.56 barrels or 300 Blackout MCX rifles
