The Perfect Metal Chamber NEO has a one-piece moulded structure and is equipped with an O-ring at the magazine connection, increasing airtightness and making feeding smoother.

In addition, the revised design suppresses rotation and allows for better centring and secure fixing with the inner barrel.

Compatible models

• Tokyo Marui M4/M16 AEG Series (NOT compatible with NGRS)
• Compatible with the First Factory Real Hard Outer Barrel series and the standard Marui barrel base.

Installation Notes

• Adjustment dial, gears and hop arm are not included.
• When this product is installed in a standard Tokyo Marui AEG, the normal rotating takedown of the receiver will not be possible.
• When installing in a standard Tokyo Marui receiver, modification of the lower receiver is required.
• Some sanding may be required to interface smoothly with your barrel base or outer barrel if the dimensions deviate too far from Tokyo Marui spec.
