Browning X-Bolt X-Lock 2-Piece Base Accessory

Accurate rifle performance depends on optics that stay put. The Browning X-Bolt X-Lock 2-Piece Base Accessory features an entirely new X-Lock scope mounting system that employs four screws per base instead of the conventional two-screw design. By securing the scope bases at all four corners rather than at the center alone, this approach enables more precise base positioning on the rifle’s receiver. The X-Lock system achieves a tighter grip between base and rifle than traditional methods. Requires Browning-style rings. Will not accept Weaver-style or Picatinny-style rings.
