No reviews yet Write a Review


B-Fast (Beretta Fast Adjustment System Technology) is the new stock adjustment device made by Beretta. With its simple and smart design it provides multiple adjustment options:

  • Max 11 mm height (parallel to towers axis)
  • Max 6" drop Max 11 degree rotation (with respect to the axis perpendicular to the stock drop)
  • Max 13mm lateral (perpendicular to the stock)
  • The new locking screws provide perfect fit to the towers, ensuring the best locking of the comb.
  • The spacers will function as "memory" for the height of the comb so the shooter will be able to change the cast without losing the height adjustment.
  • Requires installation by a trained gunsmith or stock fitter.
