Haven't had a chance to get to the range so all I can do is get config work done and nit-pick. I do have two nits to pick but overall I do want to restate that so far with all things pertinent to the function of the rifle I am happy.
Got a triggertech drop in installed without issue (drop in, zero fitment issues, happy with that). I found that I'm not a fan of the stock K2 grip (the rubberized exterior doesn't do it for me and it's a on the slim side (I like a rifle with love handles) so I went to install a MIAD grip I had in the parts bin because it's extra thicc, ran in to a couple oddities that weren't obvious with the rubber K2 on there.

The trigger guard depth is just about a mm shallow for standard ar15 spec which I think is an oversight that can be corrected in a later iteration, not a functional problem at all.
The beavertail radius is also just a hair out of spec from AR standard, the rubber k2 deforms around it with no issue but any rigid beavertail grip may need to be shaved down with a dremel ever so slightly, with the MIAD it pushes the backstrap off so that was an issue. 2 minutes with a dremel solves it. Not critical, not pertinent to the function of the rifle.
