I have the MGI tool-less Quick-Barrel Change system, so all I need are the barrel/bolt combos, and mags. It also lets me keep all the other variables the same from test-to-test. I already have the 16" Grendel set-up, with plenty of mags and ammunition components. I can help out if you want, or you can send me a 6.8 barrel/bolt combo. Let's PM. Basically, the only costs you would need to cover for the terminal tests would be the 6.8 items, and I could even ship you what you need. I've seen 6.8 barrel/bolt combos from under $300. PM me if you're seriously planning on doing this.
