I went 40+ years, shooting my AR rifles with factory triggers. I put LaRue drop ins into a couple. Wish I had done it years earlier.
+1 on the MBT.
Same here, MBT's or Geiselle G2S's for my guns. I prefer the MBT's myself, but both are serviceable for me.
I'd like to give the CMC a whirl though, just for grins.
