Yezzic Airsoft finds a Zenitco B-13 under the Zenimie brand and here is his take on this rail mount... "Here we take a look at the Zenimei replica of the Zenitco B-13 full length AK side mount rail. This is one of my go to attachments for AK-104/105 rifles as well as AK-74MN. It's durable and perfect for FSB impressions. Note: This is and older review and I plan on updating it in a series in the future."
