Pretty much what Brian said as far as why I installed it like that goes(I ran that hand stop on my "PDW"-sized M4 for a while:

How is welding to a pot metal bolt carrier going to work though....not sure I want to attempt that. I am hoping for RA-Tech to make a steel bolt carrier and I'll do more shit on that....first though I have to figure out how to put a LCT X47 selector on this...
