Heavy-Duty 6.5 Grendel, 6mm ARC, and .22 ARC Bolts
If your 6.5 Grendel, 6mm ARC, or .22 ARC bolt just broke, you aren’t alone. These bigger AR-15 calibers have a reputation for shearing lugs and breaking extractors. We sell a lot of replacements to guys who bought elsewhere first.
Ours to put an end to their troubles. It is incredibly rare that we ever have to replace one of our bolts—and when we do, it’s usually due to a bad over-pressure round, not the bolt itself. If you want a bolt that actually lasts, this is it.
Fixed Extractors, Fewer Malfunctions A lot of guys mistake extraction issues for gas system problems. Standard extractors have sharp edges and “teeth” that dig into the brass case and won’t let go on time. They also tend to have excessive extractor tension. Both of those things cause constant malfunctions. We radius the corners of our extractors so they glide over the rim smoothly and are very careful about proper tension so your brass is sure to release perfectly every single time.

It’s a nice bolt and worked flawlessly. Can’t ask for anything better than that.

I ordered a 19 inch handguard and break for my 20″ grendel. It looks great and can’t wait to shoot it. Reached out to customer service before I placed order and they were great as well. Now I’m back ordering a 6.5 nickel boron bolt face. Wish I would have added it to my previous order.

I purchased the nickel boron bolt. I love it. I think it is one of the best upgrades you can do on the 6.5 grendel
