Little update on my Atrius Dev Super Selektor
First off, they are definitely real, and they are delivering product, it isn't vaporware.

Order #6xx, placed on release date. Took about 3-4 weeks to actually get. Got it, install is easy. Had some issues in an 80% lower that likely was finished out of spec. Swapped over to an ADM UIC Low shelf. With one of my uppers it ran solid, 120 rounds no issues other than a couple light primer strike dead trigger hammer follow malfs, typical of a timing issue in a machine gun or an FRT/SS, should be solveable with buffer/spring/gas tuning.

With a different lower and upper set up I was running into issue. Had some additional issues, will clarify more later, but got in contact with Atrius and they had top notch customer service, shipped me replacement parts ASAP for the shit that I am pretty sure I broke out of my own stupidity.

Will update further this weekend.

Atrius Super Selektor arrived. Shipped from Cali. Sketch. Almost 30 days since ordering.

Need to build the host, then will throw it in and test.
