When to Replace a Bolt
Swap the bolt when you see cracked or chipped lugs, a cracked cam pin hole, a worn or peened bolt face, or extraction problems that a new extractor and spring don't fix. A spare bolt is also the fastest way to set up a second barrel in the same caliber family: headspace it to the new barrel and keep the pair together.
What Reviewers and Owners Say
“When building a Grendel or ARC it's imperative to ensure you have strong enough bolts that are in spec. This is what I run in my primary.”

FAQs
What does “Type 2 (.136)” mean?
It's the bolt face depth this bolt is built for. 6.5 Grendel, 6mm ARC, 22 ARC and 338 ARC (SAAMI spec) barrels in this family use this bolt face; always confirm your barrel's requirement and check headspace.
Is this bolt magnetic particle inspected?
Yes. Every Faxon bolt is MPI tested, a non-destructive check that finds cracks and inclusions in the steel.
Why 9310 steel instead of Carpenter 158?
9310 is a nickel-chrome-moly alloy with excellent toughness and fatigue strength, so the lugs resist cracking under repeated high-pressure cycles. More on 9310 bolts.
Why salt bath nitride instead of phosphate?
Nitride raises surface hardness and corrosion resistance and lowers friction, so the bolt runs slicker and carbon wipes off more easily.
Where is it made?
Made in the USA to Faxon designs and specifications, and headspace-checked, lot-engraved and inspected by Faxon Firearms in Fairfield, Ohio. Covered by the Faxon Lifetime Guarantee.
Can Faxon headspace this bolt to my barrel?
Faxon offers bolt-to-barrel headspace matching on FaxonFirearms.com orders that include a Faxon barrel. Read how the matching service works. If you are pairing the bolt with a barrel that was not headspaced by Faxon, check it with go/no-go gauges before firing.

Solid bolt
When building and Grendel or ARC it’s imperative to ensure you have strong enough bolts that are in spec. This is what I run in my primary.

Excellent quality and price
I built a Faxon Grendel Hog Killer and have put ~400 rounds thru it. It is solid and accurate. Shoots any type of ammo I can find, even cheap steel ammo.
