Hey guys. . .new to the forum and to the 450B. I built my first AR (in 6.8 SPC) last year based on the Mega Arms billet upper/lower set, ARP bolt/carrier, DPMS lower parts kit, PacNor barrel, MagPul PRS stock, and VLTOR rail system. . .
. . .I want to build a second upper/barrel assembly for my AR; I was planning on buying another billet Mega Arms upper as the base for the project.
Can you guys suggest quality bolt and barrel for the 450B or anything else I should know before I get started on this project?
Thanks!!!
