I have 2 lightweight guns. One is a remington 700 30-06 factory except in a McMillan Edge that weighs in at 6lbs 12oz all up with Leupy 3.5-10x40. The other is a pseudo NULA that started off as a Colt Light rifle and I sent it to Melvin and he put a Douglass barrel, timney trigger, his safety, and his Stock. Not put all together yet but should be about 6lbs and 3-4ozs when finished. It is in .270 and cost me about $1500 and you cannot tell it from a NULA.
