Ive also been following the 10-8 thread, interesting info. I deal with alot of broken bolts. Hard use M4's combined with Frangible ammo makes life hell for me during training cycle.
Ive seen broken lugs jam under the carrier key and cause the carrier and gas tube to get out of alignment. Also seen the broken lug end up down in the lower and cause broken hammer and trigger pins.
Im looking forward to some southern Indiana magic that might help with the lug shear problems................... Dont know if it will also deal with the cracks at the cam hole.
Like Ive said before here and other places you need to have training uppers and deployment uppers, both need to be set up the same, and have all the various and sundry optics and Friggen LaZers zeroed.
Also a round count(and just as important, Type) book just as detailed as you would keep for a Sniper weapon is a very good idea.
Its going to cut into some grip makers profits, and increase bolt and barrel makers profits im sure, but I cant wait to field round counters. Make M4 maintenance round count based(like aviation weapons systems) instead of gauging throat errosion or guessing about gas port errosion.
Life is too short to deal with Blonde women, or carbine barrels over 10.5 inches
