Anybody got a Alexander 50beo entry upper?

I've been looking at these for a project. Have a few questions, and can't seem to get a reply from the company to save my life. I am curious if the gas block, and reciever are same plane? Also trying to find out what length the gas system is, and whether it runs a round or triangle end cap. Any help would be appreciated.

Eyeballing it, I don't think the gas block is same plane. The end cap appears to be round. It looks like midlength gas system to me.

I have one, I have modified it, but I can check the gas length, can't remember on the gas block ground it down to fit under rail , will look imparts bin and check hand guard

So, I finally got the company to email me back. Only took four tries. It is a mid length gas system, triangular front cap, and apparently they don't know if it is the same plane gas block or not.

It's on the same plane, remembered when I first shot it last year I threw on a pair of Magpul buis that I keep around for new gun purchases
