I don't see how this is considered light weight? I just finished complete upper/lower build 6 lbs. 8 oz. Manufacturer Answer

Weight is relative and oppinions vary. It weighs just abot 2oz more then a standard M4 with our kit having a 15" free float handguard and a rifle butt stock having a 5.15 oz buffer.
