Time to bring this thread back from the archives.
Just got my new 12.5" upper together and running. Initial test look good. With my old load of 13.7 grains of 8208 behind a 160 Hornady I get full cycling (3 rapid shots) but not reliable lock back on an empty mag. 14 grains locks the mag back but might be too hot. Hopefully tomorrow I can put some over a chrono.
More to come...
