I am in the process of building a 9mm carbine and will register it as an SBR. Who makes the best lowers/uppers for this? I want to go with a Colt patterned build and a side charger. Quarter Circle 10 looks enticing. Other thoughts?
9mm build

I built a glock mag 9mm on a QC10 lower and CMT upper. Also built a colt mag 9mm on a Black Creek Precision lower and CMT upper. Both have barrels by Macon Armory, Rudy throats them so they'll feed anything. Both have Hiperfire 24C triggers. If you have any questions or concerns with your 9mm build give Rudy a call at Macon Armory 478-474-2990. He's helped me out with my two 9mm builds. They both run like tops. Being a blowback design, there a little more complicated to get running reliably. Also you could check out the PCC forum over at Brian Enos's site. A wealth of information can be found there. Hope this helps.
