Just installed it today
I received it and it had a small gash in the barrel, about the size of the grain of rice, it was at the receiver end so it will be covered by the handguard but still wish it wasnt there. wish they would notated if it has been Magnetic Particle Tested.

USNBS 10.5" S/S 5,56 NATO barrel
Assembling the upper, everything fit and did not need any washers to index the forward handguard...
