AR parts weight chart

Every six months I go through a week period of thinking about freeing up a chunk of cash and building a lightweight/ultra lightweight. Found this on one of my window shopping benders and thought it might prove useful to someone.

Pretty comprehensive chart on almost everything on an AR by various manufacturers. Not my list. Found it on Reddit.

I would be careful about building an ultra-light.

I got on a kick where I reasoned that a super-light rifle would be the cat's meow for 3-Gun, USArms, etc.-style competitions. I mean, it'd be easier running with a light gun, a light gun should swing better from target to target, 5.56 has negligible recoil (especially with a good muzzle brake). I couldn't come up with a reason not to build this gun.

I did. Got it to around 5# before optic, not much more afterwards. Pencil barrel, carbon fiber EVERYTHING, etc. That thing ended up being a PIG. When you shouldered it and tried to get on-target, it never settled. The gun moved constantly. I ended up re-building it as a 9# gun and it shoots much better.

I don't think a gun needs to be "Camp Perry Heavy", but I also don't think that ultra-light is the answer to many questions....
