Yes, the 68 should serve your needs just fine.
That being said, if you're already shooting the 65G, it might be worth considering the potential cost savings of sticking with one cartridge (ammo and / or reloading components, and magazines). It might offset the higher initial cost of another Grendel upper.
Red X Arms has 14.5" Grendel uppers (without BCG) for $400. They have bolts for $45. You could probably find a reasonably priced bolt carrier for under $100. Thus, the initial cost of a Grendel upper might be $150 more than that PSA 68 upper. But how long will it take to burn through $150 in 68 ammo or new reloading components?
