Thanks to our esteemed Dog2000tj, I know have a Territorial Gunsmiths 2nd Amendment Edition Lower, on which to start my build. With the lower ready, I will be going with the RRA LPK with Ergo grip as recommended by Canebrake in another thread. Then from there the question will really begin...What Caliber?, Barrel Length?, Twist Rate? Build the upper or buy complete? and numerous others. I am open to recommendations and thoughts of previous builders and from others past experiences. So without further ado...Let the build begin.
