Been looking at LW-upper configs for AR ...Yr' pref's?
The main weight savings will come from the barrel, there is very little to be saved elsewhere on the upper.
A polymer lower, like the Cav Arms (they are out of business and this lower is made by GWACS Armory in Tulsa now) will save you about a pound.
I'm building a lightweight AR with a GWACS lower and this barrel.

Planning to use a Bushnell TRS-25 red dot sight with plastic handguards to save weight.
