Honestly if you wanted a lightweight AR you should have bought a pencil barrel from the start. Nothing says muzzle light like a skinny barrel. Of course you can shave off quite a few ounces replacing or cutting down the A2 FSB and going with an ultralight rail/tube.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
