Thanks Rob!
Very nice rifles in here! I've been trying to put mine on a diet by adding as many polymer pieces in place of steel/aluminum. It used to weigh in at 8lbs, and it just felt like a pig sometimes. Hopefully I can shave off a pound or so and get it back into fighting weight.

man nice rifle!
I modified my cav arms build using a spikes LW carbine upper, expecting to cut the weight slightly. I found out that it actually weighs 1oz more than the BCM LW midlength upper .750" gas block I had before (moved to a different rifle now). I noticed the taper is different on the chamber end of the barrel as compared to the middy. I went on BCMs website and saw that BCM did the same thing.
My conclusion is that middy vs carbine upper, there isnt a as weight loss as I'd expect with the carbine. I had assumed that since their is 2" more of barrel milled in front of the FST it would be lighter. I didnt consider the construction differences from under the handguard because I assumed it was the same. I wonder how much less weight a .750" block upper is vs an upper with .625" block. Obviously a middy handguard will weigh more than a carbine handguard by a couple oz so that has to be considered. But for anyone trying to make a LW build and deciding between a middy or carbine. I havent notice any significant difference. The carbine can possibly weigh just as much or more.
Notice how there is more metal near the delta ring on the carbine. Any idea why the carbine has it but the middy doesnt?

I'd be willing to think that the carbine upper doesn't have the same barrel profile as the middy does. It appears that the carbine actually has a thicker barrel profile overall. Looking at the FSB on the middy it steps down and appears thinner prior to and post of the FSB. The carbine barrel appears to be around .730 before and after the FSB so that probably makes for the visual difference as well.
