My opinion on ARs these days is, "parts is parts".

You can buy one with the particular features you want,..but the bones of one is going to be as good as the bones of another.

I bought a Bushmaster QRC a while ago just because it had the very light barrel and no sight on the front gas block. (scope is a given for me these days) It tips the scales at a tad under 6 lbs and is bare bones and bargain priced.

It's exactly what I wanted in an AR,..basic and very light.
