Just cleaned after a trip to the range.
Runs fast and finally 100%.
She’s mean.
Modded wire stock so it doesn’t collapse, FF3 sight, Octane9 3lug, Lage internals, my Z-mag collection finally broken-in and tuned to this gun. Not one stoppage at what had to be 1500+rpm for 600 rounds (without Octane). Special thanks to Dykem machinist layout dye, and pliers to bend an upper receiver flange/tab that had strayed unbeknownst until now, to Dremel for grinding the stock bolt where the forward hood slides closely down the barrel, and the humble needle-file to address the mag feed lips.. All together finally making this thing a true joy I no longer worry about going bang-really-fast, at least until the next time I shoot it.
