So for the first time in my life a saw and handle for real a lower receiver.
It's lite
I installed the DPMS LPK that I got from Brownells and the A2 Stock kit from a CGNer
I followed these instruction

Along with the DPMS schematic in the back or the package. It's fairly easy to do. Even for someone like me that never handle a AR .
I used the vise-grip and electrical tape method for the rolls pins with a combination of masking tape for protection. I also did this on my computer desk so it's pretty easy. no speacial tools needed here. My lower looks as good as new , no nick or chip. Blue Line lower was PERFECT no defect or problem during installation.
After that it was pretty straightforward, 2 push pin and bingo

I still cant belive I did it. Make me wanna get another Lower.
