What ever you get, put a suppressor on it, a DPT over barrel suppressor is a good starting point, and if you get a smaller caliber (.223 6.5Grendel etc) that some have suggested, a DPT mini is plenty of suppression with a bit less length and weight.
You haven’t asked about scopes but it is a very important consideration. A 3-9 is a good starting point but if you want a bit smaller and lighter, 2-7 is a good option too. If you want to keep it simple, fixed 4x is just as good as anything else 80% of the time and better than anything else more than 50% of the time.
