Item #758 is a bolt carrier with a 7.62x39 bolt;

Question: Will this bolt work on a Grendel barrel?

Thanks

No. Headspacing wouldn't be correct.

Grendel chamber uses a recessed bolt face. Doubtful that a 7.62x39 bolt with standard recess would close completely on a cartridge in a Grendel chamber. And even if it did, it would still potentially be unsafe. Not recommended.

Some variant chambers have used a 7.62x39 bolt, but not the Grendel as far as I know.

Thanks. I need a bolt carrier and thought I would get this one and have an extra Grendel bolt to boot... Thanks for setting me straight.
