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.

Good price for a Grendel bolt and on time delivery. It works like it should, what else can you say about a bolt? I would buy from here again and will recommend this site to anyone who might be looking for Grendel related stuff.

Slick finish. And most importantly it saved a barrel from being sent back. The bolt I had for it closed on a go gauge and no-go gauge. Bought this to see if would make a difference and it did. Bolt only closes on the go gauge now. I bought 2 so I’ll have a spare in case I wear the first out, which I doubt will happen.

Currently running 2 of these in 6 arc builds without any issues. They both run super smooth on the finish and no blems in the machine work. Don’t hesitate to use these quality parts.

I have dealt with Andy before and this was no different. Great quality bolt, etched with cal. Reasonable price and fast shipping. If you call with a question you are likely to get the owner. Terrific company worthy of your business.

22 ARC Build. This was the last piece of the puzzle I was needing. Very nice bolt. Has worked flawlessly in every way. I will order more in the future.
