Bolt Shear
Ive been dealing with a whole bunch of M4's with sheared locking lugs on the bolt.
Every one of them the locking lug to the left of the extractor (looking at the bolt from the back side) sheared off. Round count was unknown, "Alot", "2 Ass loads" ect were the best guess. Most of the shooters had been visiting a guys range in TN, who likes TO TYPE IN ALL CAPS
My question is prompted since it was all the same lug that broke. Should I be worried that I have a batch of bad bolts?
the weapons in question are all M4A1's with stock FA BCG's without the Crane Extraction enhancement kit installed.
Life is too short to deal with Blonde women, or carbine barrels over 10.5 inches
