PBB Helical 1-12 Fluting

[Timberline001]

23 inch .308 blank .810 taperless 3lbs on the dot. The 1 in 12 helical flutes cut 8 oz. They accidentally shipped it first without fluting so I was able to weigh exact weight reduction.

I believe this is an 8 twist

What’s the weight compared to the factory barrel it’s next to?
