r/Springfield_KUNA

I already own my Springfield Kuna and a Holosun HE510C-GR

Let me know what you think of these components before I start ordering; if anything should be swapped out, or if I'm missing something. I don't have any other Super Safety guns (AR-15 or otherwise) so starting from scratch. I'd prefer parts that don't require modification or extra 'hand fitting'.

Redacted Arms flat trigger pre-cut w FCG kit (rumor has it these are ~4.5# instead of mil-spec 5.5# )

Anti-walk pins (see edit)

Grip B5 with no beavertail

Edit:

I read that I do not want the non-rotating anti-walk pins on the ASDesigns site, so getting these instead.

Also scratching out the Redacted Arms group for possibly this, to get my flat trigger.

I'm not sure what I'll do about reducing the weight while keeping it SS compliant. I suppose I could always bite the bullet and buy the pre-modified Geissele but those are like a ridiculous 3# pull or so.

I just came across this video. So is this a requirement for all super-safety options with the Nexus? What about if you don't have a super safety, but just the Nexus lower?

Edit: Second question. Do ANY pre-cut triggers work with the super safety trip and ARC-Fire v2? Or just certain ones. Redacted Arms makes one, for instance. I'm trying to find something slightly better than mil-spec without paying for geissele prices.
