About
The Sibling Rivalry Project, founded by siblings Sako and Tamar, benefits Angels of America's Fallen, a charity that supports the children of fallen service members. Ten percent of proceeds go to the charity; production pieces reach buyers by lottery and auction.
The Shirogorov entries are the F3 and the Stellar CF, each built in a Sako version and a Tamar version. The project also includes a Pro-Tech and a Koenig custom that fall outside the Shirogorov catalog.
