I paid for a second run slick slide, with no known issues with said trigger. I clearly got a first run upper that I didn't order. That is ATRS fault...
I specifically canceled my order for an SLR after hearing of people having to dremel receivers and needing to glue them together. I clearly got sold something I didn't pay for and now I am paying for it with being given option to dremel my upper or send it back after an entire years wait. You fan boys are missing the point here.... I avoided SLR for the same problems I am getting with my ATRS.

They didnt change the rear hook profile until they started making second run fa uppers I believe. It's been a known issue for almost a year that the original slick side uppers do not work with the TT adjustable triggers. You have 5 options. Shave the hook, shave the trigger, send it to atrs for a mod, pull the rear bar out and put a kns pin in its place or buy a new trigger. I have a Timney calvin elite I'll trade straight across for your diamond. It fits and functions 100%. Its not atrs fault the trigger tech trigger doesnt fit. Their trigger housing is just to big and doesnt fall within the mil spec foot print that the ms was designed to accommodate.
