6.5 grendel, odin works 18" barrel, h3 buffer, thunder Beast ultra 7. Personally, this barrel is way over gassed, without the adjustable gas block, it will go maybe 2 rounds without jamming. With it, I'm averaging 50 rounds between jams, not great, but usable. I'll either play with the buffer more or rebarrel. For comparison, I've seen an Alexander arms upper go from no can through a 6.5mm ultra 9 without a hiccup.
Most ars are over gassed (can help with reliability with cheap ammo) and can benefit from an adjustable block even without a can. An adjustable gas block will also help reduce ejection port noise, giving you the most of your can.
