Will a 22 Grendel work in a AR-15 Platform or does it need an AR-10

The AR15 is what is needed. The 22 Grendel is simply a 6.5 Grendel necked down. Use Grendel magazines. The new 22 ARC you are reading about is the 22 Grendel/22 LBC with plus or minus a 0.001 here and there. The dies will be usable from the ARC to load the other two as will the brass. I've been shooting a 22 LBC for over a decade so the ARC is not a mystery..lol

In my 224 Valkyrie, I can get 3400FPS with 25grs of Re#15 behind a 60gr bullet 2890 pushing a 75gr ELD with Re#15.5 and with 28grs of Alliant Power Pro 2000MR pushing a Berger 80.5 Full bore at 2950. All of these group 3/4-1.0MOA out of a W.O.P 23" Krieger bbl. Will this 22 ARC outperform this?
