If all that is needed is a new barrel extension why aren't we using the "magnitudes stronger" bolt design alluded to? Imagine if the maximum pressure could be increased to 60,000 PSI!
I found XD750 and Titan bolts from AR15Performance.com that use a custom barrel extension and are available only with a barrel purchase. Have these been independently tested?

And yet the barrels are absolutely wonderful.
I have an 18 SPR barrel in 6.5 grendel with his enhanced bolt. I have zero worries about it. Its a quality part.
My .223 and 7.62x39 barrels from him have all been tac drivers.
Its a shame hes out of the grendel game. As far as I know I got one of his last grendel barrels.
I wouldnt buy anything from AR15 Performance, imo he pushed the platform in his work to extremes. But thats me, I know people like his stuff and I know people who dont.
Hell you cant even bring his company name up on AR15.com. Theres nothing wrong with the Grendel bolt, if there was then the DOD wouldnt have picked up the 6mmARC for some units.
Can you break a Grendel bolt sure, but if you source the item from a reputable source and use it within the limits then youll be good to go. Hell 5.56 bolts break or lugs shear off and its got more meat.
