Actually, this is what I said in the other thread concerning potential weight reduction for the Templar:
"The thickness of the monolithic Handguard has already been shaved down as much as the designers thought prudent, so cutting it back a few inches would likely save grams rather than ounces. Turning down the steel Barrel forward of the Gas Block could save more substantial weight, but at the risk of degrading the currently excellent accuracy.
I think that Fluting of the entire Barrel length is the answer for weight reduction in conjunction with hollowing/recessing the sides of the Bolt Carrier and removing the Steel Reinforcing Plate on the Left side of the Upper Receiver. Fluting not only reduces weight, it also has the benefits of:
- Maintaining the original Barrel rigidity, and
- Increasing the surface area available for cooling, thus resulting in more rapid heat transfer to the atmosphere."
I see no problem either reducing the size of the Upper Receiver's Steel Reinforcing Plate, or eliminating it altogether. A properly timed and toleranced AR180 style rifle should have no contact between the Bolt's steel Cam Pin and the Aluminum Receiver Wall in any case. I personally believe that the hype about "steel on aluminum contact" is excessive, as no such contact ought occur in a properly designed and assembled firearm. That said, if folks insist on having a steel Reinforcing Plate in the Receiver Wall, make it 1/3 the length and focus just on the area where the Bolt Cam causes Bolt rotation, since that is where such contact occasionally occurs. You could save a bunch of fairly thick steel (and its associated weight) by eliminating, reducing and/or thinning the rails of the Receiver Reinforcing Plate.
To summarize, I believe that you could knock 2 lbs off of the Templar by Fluting the Barrel, Eliminating or reducing the steel Upper Receiver Reinforcing Plate and Hollowing the sides of the Bolt Carrier. Attack the Templar's steel content, and you will achieve the greatest weight savings based on material eliminated.
