Lightest Factory AR?

[man32ahan]

What’s the lightest factory AR you’re aware of?

Caliber doesn’t really matter but I’m assuming 223 will be the lightest.

Not interesting in a frankenbuild with pieced together parts.

Thanks in advance.

Some of the old colt SP1 models from 20+ years ago were in the 5 pound range.

Fostech took over were mag tactical left off making magnesium lowers and uppers. I can’t remember their actual #’s but worth checking into.

Going the pistol or SBR route should save a lot of weight considering the barrel is where most of the weight is.

V Seven has a ultra light weight ar-15 with unique alloys and several titanium parts.
