There are a couple of youtube videos of this rifle. I watched because I was curious about how reliable the ejection would be with the rimless 7.62 cases.
The Lee-Enfield design works fine with a rimmed case. I have never fired a 7.62 version so I wondered how well the LE bolt ejected the rimless case.
At 2:06 into the video with the camera behind the shooter you can see that the ejection is very positive out and away from the rifle with little effort.
Reminds me of a 700 Remington ejection.
The earlier video showed positive ejection but you could not just how far away the the rifle the cases were ejected.
Anyway I was digging around in Marstar's web site and found this picture of the AIA bolt head. It's ejector design answered my question about ejection with the 7.62 case.
