New owner quick-start
- Confirm it's a 457, not a 455 — stocks, triggers and rails differ.
- Torque: stock screws 3.5 Nm; barrel screws 5.5 Nm, tightened after the mag-housing screw.
- Use a clamp-on rail instead of dovetail rings if you see scope slip.
- Barrel swaps: headspace-check every barrel; CZ says a gunsmith should fit Mini-sets.
- Threads: US 1/2-28, non-US 1/2-20.
- See known issues and the ~$197 budget build.
