The "Sheep Cut" refers to the cut of the ejection port. This Action is their light weight version.
I use Talley Onepiece Rings to keep weight at a minimum.
You can also get a 20 MOA rail from Defiance if you prefer.
I have built a dozen rifles on this style of Action.
I just finished a 28 Nosler with this same style Action. I used a Proof Sendero Lite, a Manners EH1, BDL Bottom Metal, And a Holland QD Muzzle Brake.
Total weight is 7.1 pounds.
I can email pictures of some of the rifles if you would like to see them.
Yes, I can ship FFL to FFL.
