Robb, you have absolutely outdone yourself with this, it is beautiful! I cannot wait to install and try it out. The price point is fantastic as well, thank you!
A vise will make your life easier. As for heat, I used a MAPP torch but don’t apply the heat directly to the receiver (you will melt it). Rather, apply the heat indirectly onto the steel recoil tube near the retaining nut.
It feels solid, but I have only taken it out to shoot once.
I was able to leave it on when I disassembled it to change out my recoil tube, just loosened the bottom brass set screws.
