Update on my RPR.
I have the new HG installed, the upgraded Butt Stock (Magpul PRS3), and some other things. The new Timney 2-stage trigger will take an extra day because, much to my frustration, you have to canibalize the original factory trigger and put some parts from it into the new Timney trigger.

I don't understand why they couldn't just build it with the parts already installed, although I suspect these particular parts may be specific to the model of the rifle.
Anyway, I'll keep y'all posted on the progress. I have an appt. for membership safety check at the JTAC ranch near my house on 07/17. They have some nice property there.
We'll see.
