Lightweight Ar build suggestions?

and I wanted to toss an aero me41 lower on an atlas upper with no forward assist upper I found online with a 16 inch pencil barrel and a 15 inch handguard.

I’d suggest a 14 inch barrel with a pin and weld flash hider up to 16 , it saves you some weight as well

Look at the WWSD carbines from Brownells and KE Arms.

I've been considering building one of those.
