Beretta Beretta Semi-Auto Drop Adjustm E01630

The Beretta Stock Drop Adjustment Kit is an essential, multi-piece factory hardware system precision-engineered to customize the ergonomics of your 12-gauge hunting or tactical firearm. This drop-in system includes specialized high-impact polymer shims and heavy-duty steel lockplates configured for 50/65mm and 55/60mm adjustments. By altering the physical interface between the receiver chassis and the buttstock, the components allow marksmen to fine-tune the comb height and drop at heel to align perfectly with their natural eyesight plane. This corrective geometry is highly recommended for tactical applications or dynamic shooting scenarios where high-mounted red dot optics or thermal scopes create uncomfortable cheek weld gaps. The kit guarantees seamless, cross-platform functionality with a wide spectrum of leading firearms, including the Beretta 1301 Tactical, A400 series, A300 Outlander, and legacy AL391 Urika models.
