New Legos! DPMS improved A-1 upper for an XM-177 style build 1/9 11.5 inch barrel w/ permanent FH from Tony's Customs. I may choose an older style CAR stock. I had to modify the handguard retaining ring to fit round handguards. It matches up with my New Frontier poly lower very well, but I am shopping around for a DPMS lower to complete the build.
