Nice job. I see the Adams carrier is 7.5oz on their website and I thought SupArms carrier was 9.45oz which is just 2oz different. Is that what you got on the scales between the two?

I haven't really checked, but it did make it lighter, at about 2 oz. If all goes well I'm going to be buying a Titanium Carrier in which I will put an Adam's Arms Piston Carrier Key on, w/ higher torque screws than the one the key comes with, which will reduce the weight to around 5.7oz (another 1.7 oz shaved). I have a PWS Anti-Tilt Buffer Tube on my builds which should solve carrier tilt issue seen with piston carriers w/o skis.
I also have a Wolff Reduced Power Springs and Taccom LW Buffer in which I hollowed out to 0.9oz. I'm all about the new lightweight setups now so 2-4oz is a hefty amount for us LW guys. My entire reasoning to light up this rifle (even more than it is) in comparison to her sister DI rifle is to lessen the margin of weight when comparing both builds.
I called Superlative Arms up about a week ago to ask about their low mass carrier in which they will release and told him my plans to dremel the Piston Rod in order to use other carriers. He obviously advised against it because the Piston Rod is Nitrided H13 Steel, however the Nitriding while raising the RC Hardness and toughness, won't protect shitty metal and H13 is pretty damn strong to constant forceful impact. Since impact will be less with the lighter carrier/spring/buffer weight I'm not too worried about the Piston Rod breaking or having a catastrophic failure such as cracking or worse.
