ok, friendly advice, be VERy carefull to put the little arm that turns the rotating BB port right. I had it backwards, the screwhead was poking 2 mm outside, instead of being flush in it's recess, and as a result i've been sweating swearing, and busting my hands for over 45 mins with nothing fitting or just jamming.. It was just one of those moments, after fixing the mistake, when everything just slid into place witout any effort...

question for OP( or other owner): does the bolt stop open when mag empty/no mag? because on Uncompany's site it says: "-Empty Firing Mode, will not hold bolt open with empty magazine / without magazine"
