[QUOTE="5.56×250, post: 2481560, member: 110162"] The Grendel bolt face is only rated to 52k pressure. The bolt upper uses a 3 lug bolt with plenty of meat to go 62k. Whole different ballgame on velocities than the semi setup. Don't get me wrong, I love my Grendels in semi auto form. I just want to push the ARC as hard as I can without worry on bolt head breakage . This will be the 4th upper for my pet lower receiver and the only upper I didn't build myself. I have 22lr , 223 Wilde, and 6.5 Grendel in semi auto uppers . I really don't expect better accuracy fromm this new upper. All 3 of the others shoot sub half MOA. I just want a slick bolt gun on the same receiver I've had all this time with. [/QUOTE]
