Mausingfield Fire Control Compression Tool.
Tear a Mausingfield apart once and you'll soon discover just how impressive the spring rate is on the firing pin.
LRI has an elegant/simple solution for this task. Our compression tool fits comfortably in your hand and effectively delivers the ability to compress the spring and unload the unique castle nut/washer used in the assembly. 100% CNC machined from steel this is a "buy it once" tool that'll last a lifetime.
For those who have as much affection for tools as they do guns, we also offer the compression tool in a Color Case Hardened finish!
