The First Factory Silencer Attachment NEO R is a silencer attachment designed for use with Tokyo Marui's standard electric gun MP5 series. It's constructed from a lightweight yet durable aluminum alloy, and it's compatible with 14mm CCW (counter-clockwise) threads, allowing you to attach various optional accessories. Additionally, it shortens the muzzle compared to the stock configuration, enhancing overall maneuverability. This attachment is compatible with most Tokyo Marui MP5 models except the Next Generation Recoil Shock (NGRS) variants or the SD variants.
