finally sent my old sloppy 6 year old RRA 2 stage in. they just sent me a brand new NM trigger without any questions or fuss, so that was swell.
first tried to install in in my 308, and it wouldn't release the hammer. could barely even get the dico to catch.
dropped it in a 556 lower, and similar results. disco would catch easy, but wouldn't drop the hammer.
dropped it in a different 556 lower. this one will drop the hammer, but not consistantly, and only after about 15lbs.
narrowed it down to the tail hitting the bottom of the selector. trigger runs fine in all three lowers with the selectors removed. pretty sure all three selectors are from different places (DPMS, PSA, DTI if memory serves) id like to try it in a factory lower before I lay blame though. anyone seen this before?
