These fasteners secure the receiver of a CZ 457 rifle to its stock. Proper torque and installation are essential for maintaining accuracy and structural integrity. Typically, two of these specialized screws are utilized, strategically positioned near the tang and the front of the receiver.
Correctly fastening the receiver plays a critical role in achieving consistent shot placement. A secure fit minimizes vibrations and movement between the action and the stock, ensuring the rifle performs as intended. Historically, variations in screw design and material have reflected evolving manufacturing processes and engineering advancements in firearms.
