Trevor, good of you to reply.
My stock is a PR&T which I just received earlier this week. It weighs in at 4 pounds, 10 ounces but it is unfinished. I suspect the weight will go up to about 5 pounds with the finish and the bedding.

The NXS is 34 ounces and the Panda is 30.5 ounces. Nightforce lists the BR 12-42 at 36 ounces, so heavier. The NXS has 45MOA of elevation. I am considering the Kelbly rings.

I am considering getting the Sinclair 3gen bipod which is under 2 pounds. You are correct that I have the 2gen model and it is heavier, closer to 3 pounds.

I'm not sure I follow your issue getting to 300 with 20MOA. Just for the record, I do not plan to use this rifle for anything below 600 yards and it will mostly be 1000 yards.
