Custom 6 ARC Conversion

I guess if you look at it as a large frame with adaptors perhaps, I don't because it was designed to operate this way, not adapted from one to accept another. I don't really plan on shooting large frame calibers from this one, as I have another one that has quite a selection of bigger cartridges like 308, 6.5, 450BM and such.Large frame with adapters, no? Take the adapters out and run it with 308 mags. I've never used Geisele mags but Grendel mags in general leave a lot to be desired. There are plenty of higher quality 308 mags. ARC has capacity constraints, GT doesn't. Your platform doesn't have the 52kPSI ceiling an AR does. Port pressure of GT is pretty close to 308, use all of the 308 parts minus the barrel. Why get hamstrung by the adapters and case capacity of ARC when there's native solutions? As I understand it, the accuracy issues don't appear with lower weight projectiles, maybe you can speak to that?
I was unaware Grendel mags left anything to be desired, they have always worked just fine for me. And I am not really concerned about capacity with ARC or GT, for the most part I shoot low volume strings of maybe 3-4 rounds. The only reason I wan't an ARC in this platform is to have the ability to shoot 100gr class bullets for varmints and smaller big game. I mostly shoot .223 through this rifle for affordability and efficiency, the ARC is a slight step up in cost and bullet weight. The GT would be a bigger step up, but I already have that option. Plus I don't want my expensive GT brass getting beat up and damaged by autoloading.
I haven't noticed any kind of accuracy issues with the ARC be it 58gr up to 105 grain. I haven't tried anything bigger like the 109's or 112's that I shoot in the GT, mainly because I get the Hornady 105's for dirt cheap and they shoot fantastic out of all my ARC's and the GT too.
Curious how you know what the pressure ceiling is on my gun? I thought AR's were higher than 52k, like 58k, and since the WLVRN shoots higher pressure cartridges over 60kPSI I don't understand where that point is coming from or how its relevant.
