I was finally able to install and adjust my RSA trigger. I tested it out, but only did so with a couple of rounds. I need to take it out soon and test it again, now that the Loctite has set the adjustable screws.
I don't recall if the factory preset the trigger as a single or two stage. I followed the instructions (some indepth at that) to set it up as a single stage trigger. The instructions seem somewhat complicated, but the key is to read and understand what each part of the trigger does. Then you can adjust/tune the trigger to your liking.
It feels really nice, and most importantly, the hammer hit the firing pin correctly. This will save the pin from the kind of damage that the original incorrectly ground hammer was doing.
I'll post another video and report once I try it out again. Sorry, I didn't have better info.
