Blank locking bolt intended for use in Perazzi models such as MX12, MX2000S, MT6, High Tech S, and other 12ga-frames whose triggers are fixed in the receiver (non-dropout). Also works in regular MX8 type receivers, and is required in guns with dropout triggers and coil springs.
Installation requires either a milling machine or Giuliani's own lockingblock fixture: https://www.targetshotguns.com/products/accessories-giuliani-2675-593bf2c2-c86e-42d4-bf11-24ee4be52246
