Most competition actions make you choose. Either tight enough to shoot small groups, or tough enough to hold up through a full competition season without loosening up. The Fuzion holds both. Machined from pre-hardened 416R stainless steel, it stays dimensionally stable under high round counts. Tight-tolerance machining and a one-piece 4340 chrome-moly bolt give it a smooth, repeatable feel shot after shot, match after match.
