I want to say they shaped the receiver in some optimal way and reduced the ejection port size to as minimal opening as possible. Basically incorporating all the learnings over recent years of how to economically erase sourced of inaccuracies. Plus it has a decent trigger due to its two stage design.

It would be appreciated if they would make a “nice” version incorporating all their learnings into a product you could be proud of and pass down. I guess there’s just a small market for what it would cost
