Sheared bolt lugs

[LRRPF52]

AR Performance makes a special 6mm BR bolt and barrel extension, but I think their improved bolt designs for 5.56 and 6.8 slip into standard extensions. Harrison seems pretty committed to the 6.8 SPC, and has been considered one of the go-to guys all along for doing the 6.8 SPC chamber right, while certain makers jumped the gun and screwed the pooch royally with an 80 degree hand-off from the leade to the rifling, resulting in some serious kaboom. I'm not really interested in investing in the 6.8, and I wish ARP would offer conversions to 6.5 Grendel with his bolt geometry, even if it meant doing an AR10 style bolt face/lug and matching extension like Oly and the WSSM's.

Can you compare an AA Grendel bolt face recess dimension to the LMT enhanced 7.62x39 bolt face recess? Do you use the LMT 7.62x39 as a drop-in with AA or other Grendel barrels?
