In this video is a demonstration of the Escort AK-105. It was upgraded by a later 3rd party known as Daytona Gun based in Hong Kong. Escort internals are done with brass which is softer and has many prop and con’s. Daytona gun AK’s are CNC’d made from steel that are knickel plated. you can hear the difference from the report as they fire. check my Daytona Gun AKMS video as well to compare the two.
