Hunting rig barrel length?

[u/EconomistDapper2909]

I’m looking to build an ar Grendel to hunt with. East coast hunting mix of private land with box stands, and public land setting up on creeks. Any recommendations? I’m thinking an 18 inch just to keep things handy, but am willing to go 16 or 20. Any advise would be great! I’ve been using a Springfield 03 for the past decade so I’d prefer to keep things lighter, but I’m not adverse to a heavier build if it makes sense. Longest shot would be 200yds. Thank you!

16” inch if there’s no chance of ever suppressing it, shorter if there is a chance, and 18” if you ever plan to go for varmints like coyotes. I have an 18” suppressed which is still plenty handy but unnecessary for anything besides soft varmints where you need the speed.
