only pic i am able to post is older and you cant see the body to well. Here is the link
It does seem to be a bit of a curiosity (besides the fact of everything else on it). It is pretty old i believe and i have not seen this before but i feel like its not unusual. The feed chamber is completly sideways. You can easily imagine it i hope once you can picture it without the Qloader feed neck on it. I also hope you can tell that is not a twistlock by the certain form and looks of the barrel. I do believe i might be autococker threads. I never looked into it since the barrel on there is great and once i have a great amount of spare cash i might buy a dye carbon fiber 20" boomstick. But that wont happen for a while so it doesnt really matter for me.
