My trigger was horrible, and two plus coils snipped didn't do much. I couldn't take any more off as that would take me out of compression so I ran a 10-24 set screw up through the stock spring's hole (after removal). Threaded a bit of a new spring over it and it was better, but did nothing for overtravel.
I yanked that setup and ran a longer than needed cap screw through and adjusted for no overtravel. Sear hung up after tripping and trying for bolt removal from receiver. So I backed the screw off a tiny bit. I then swapped that out for a button head screw that projected the same amount above when coming to bear.
I then ran a slip over coil spring.
No the spring isn't trapped by anything other than assembly, but once set who takes them apart?
Did work on my sear angle/face, got the creep out.
Impact in multiple directions shows it safe.
Might be 3# or under, haven't scaled it yet. Usable but not what I really like. Eh it's just a beater yote rig, good enough for who it's for I guess
