I found a very nice 300 BO upper on gun broker and this is how some dealers will get rid of excess inventory. The ammo is coming down you just have to search for deals. Here is an example:

Also, you can use your same BCG and charging handle from your 5.56 set-up so if you have a couple of these laying around, it is one less thing to purchase to get shooting.

I have 2 complete lowers ready to go. I'm thinking one will be 6.8 and the other 300 blk.

The 762x39 will be a cool one. Go for it.
