I'm just starting my first AR build. Got the parts for the lower receiver, now looking for an upper. Since I already have a 5.56 upper, I'm thinking about the 5.45 X39.

Here it is. It is a 5.45 X 39 upper from S&W. I still have more work to do. Replace Gas block, replace handguards and free float.
