BAT’s model MST started as a model M action, they moved the bolt stop forward and shortened the load port. This is perhaps the best option for many cartridge’s used in 1000 yard matches such as the short Magnum cases. Improvements over a standard model B include:
  • More bolt lug surface area, creating a stronger action.
  • Larger barrel tenon for more support around Magnum cases.
  • More bedding surface
  • More action screws (3) 1/4-28 and (1) 10-32
  • More support in the rear bridge making the bolt cycle smoother.
