Backcheck Tools

Along with superior backchecks, WNG provides an integrated system by which to install backchecks into an action properly.

The location of the backcheck, under the hammer tail, is every bit as important as the design of the check itself. The full benefit of a well designed backcheck cannot be realized without good backcheck geometry.

The WNG backcheck installation system encompasses tools, procedures and parts, carefully designed to work together. Good tools allow the technician to take advantage of the features designed into the backcheck.

To tie the concepts, parts and tools together, WNG provides a comprehensive written procedure. Full detail is provided so that anyone from a beginner to an advanced rebuilder can benefit.

A comprehensive solution ensures good backcheck geometry and thus good backcheck performance.
