Great for new builds & maintenance

A must have when building an AR-15 and for monitoring firing pin wear. A firing pin that exceeds the maximum bolt protrusion is unsafe and must not be used.

Time saver

Armorer for our dept, this tool saves time. Yes you "could" probably make one but why bother. Fairly priced & double checked specs are as marked.
