Home Forums Hunting & Shooting AR and Tactical Rifles The Original Grendel is back

Also its also a myth that the Grendel bolt made with 9310 steel as all Grendel II come with is rated to 53K. The Grendel bolts made of 9310 steel are not rated and I've talked to a couple machinists that make Grendel bolts and they are confident they can do 60K without issues. The MILSPEC 5.56 bolt made with 158 carpenter steel is rated to 53K but Grendel bolts have never been rated. That 53k "rating" gets thrown around but no study to rate the bolt has ever been done.
