6.5 grendel bolt type

[Dt219]

I recently started building a Grendel like a dummy when parts is non existent. I bought a Er Shaw barrel since they had a 18” in stock and on sale. It came it and looks great I read on their website they used a 7.62x39 bolt Not a type 2 bolt, is there any down side to this ? or less desirable ? Or less accurate ? Also has anybody here shot any of the Shaw barrels
