Personally, you haven't explained a single thing about why you "need this" trigger. You don't have a need for it. It shoots when you pull it, and it shoots when you let go to reset it.
I've asked you repeatedly, very directly... "WHAT DO YOU WANT THIS GUN TO DO FOR YOU?" I've also asked you repeatedly, "WHAT IS YOUR GOAL FOR THIS GUN, TO DO FOR YOU?"
Nothing. Crickets.
You keep dodging those questions, and don't answer them.
I asked you why - you refuse to answer.
No, you never did, which is why I asked. So get to it, and explain it already.
You refuse to read what I'm directly asking. And, refuse to answer directly what I'm asking.
Pick the right one - I recently heard that he is making a .308AR charging handle.
Get the right gas tube.
Almost ALL lowers are marked that way - even if they don't have the shelf to support a full-auto trigger - manufacturers mark them that way anyway. Not, ON YOU, go drag your ass our and research shelf height, in lowers, and full-auto triggers. Have fun with that one.
