My MDI set came with several issues, 3 of them I'd be able to fix myself but there are 2 that bother me so I'm sending it back.
1 - barrel won't fit the upper (I just tried freezing the barrel and heating the upper)
2 - BCG feels lose inside the upper, it rattles, I'm not sure how lose it can be without issue, but compared to my AR it is very loose. You can move it sideways with your fingers through the ejection port.
When I first saw the MS I thought of cancelling my MDI pre-order and ordering a MS, but MDI was promised to an earlier date. If I had vaguest idea of the issues and delays I'd have done it.
The whole idea of having a screw and heli coil as the retainer for the upper is a terrible design.
Prone to stripped heli coil, vibration loosing the screw, etc...
Also the upper can still move forward a small amount due to the size of the hole if it not completely tight or loosens off.
As opposed to the hook and pin on the ATRS which will not allow this to happen.
Helicoils are routinely used in black rifle offerings. Here is an A2 Receiver extension so it’s not uncommon.

ATRS doesn’t employ woman in tight yoga pants to do their machining. MDI for the win.
Wearing yoga pants in public, or leggings is gross and trashy.You obviously have never been to any of the events ATRS attends. They have a really cute lady who is also very knowledgeable on firearms working for them although not in tight yoga pants unfortunately.
Spandex is a privilege not a right and unfortunately is not observed much any more. Even those shown hosing down a mill.
It's good to hear some positive stories too.
At the end of the day, if it makes you happy and it works then that's great.
There is usually more news about something when it is negative, rare to hear the positive.
