WBP® Firing Pin for Jack 5.56 and Mini Jack 5.56

This WBP replacement firing pin is designed for compatible Jack 5.56 and Mini Jack 5.56 rifles chambered in 5.56×45 NATO and .223 Rem. It can replace a worn or damaged factory component or be kept as a spare part. Because WBP 5.56 rifles may use different firing pin configurations, compatibility with the specific bolt must be confirmed before installation.

Designed for WBP 5.56 Bolts

The firing pin is intended for compatible WBP bolts used in Jack 5.56 and Mini Jack 5.56 rifles. Its geometry is specific to the WBP 5.56 platform and should not be treated as a universal AK-pattern component.

Replacement or Spare Component

A damaged or excessively worn firing pin can affect primer ignition and the safe operation of the firearm. This replacement component can be used to restore the original bolt assembly or carried as a spare for maintenance and repair.

Not Compatible with Standard 7.62×39 AKM Firing Pins

This component is intended for WBP rifles chambered in 5.56×45 NATO and .223 Rem. It is not a standard AKM firing pin for 7.62×39 rifles and should not be installed in bolts designed for another caliber or firing pin system.

Verify the Firing Pin Configuration

Before installation, confirm whether the specific rifle and bolt use a spring-loaded or free-floating firing pin. Differences between bolt and firing pin versions may prevent correct fit or operation even within the same general rifle family.

Professional Installation Recommended

Installation, firing pin protrusion, free movement, and overall bolt function should be inspected by a qualified gunsmith. The firearm should not be used until correct fit and safe operation have been verified.
