Just ordered a Aero Precision 6.5 bcg with bolt. Bolt is made of 158 carpenter instead of the 9310 i notice most others are. Is the 158 going to hold up fine its a hunting rig for a buddy that probly wont see a lot of rounds. Im sure they wouldnt be selling it if it wasnt up to par, thanks again guys

Faxon website FAQ's has an explanation...
C158 is the mil-spec, 9310 is supposed to be better-than...

Heat treating and quality control are more important than the alloy, as long as the alloy is sufficient for the application.
There are various types of 9310, with one of the Aircraft-grade 9310s being preferred.
Again, if the manufacturer chain and final point of sale business don't have a handle on heat-treating and processes, the part won't hold up.
Several parts manufacturers have figured this out for 6.5 Grendel already years ago.NRA Basic, Pistol, Rifle, Shotgun, RSO
CCW, CQM, DM, Long Range Rifle Instructor
