Pacific Tool & Gauge Firing Pin Compressor Tool. This jig is what we use for modifying or assembling our own firing pin assemblies, now you can own this easy-to-use tool too. A vice is not required for use, a flat stable surface with a thick corner is all that is required. The blue handled push rod has three holes for pinning the tool in place: for long, short, and compact length firing pins. The bolt shroud is threaded on to one end of the jig, the firing pin and mainspring are assembled into position, pushed through the shroud with the push rod, locked in place with a customer supplied pin or punch through the appropriate hole, and then a cocking piece can be easily added or changed. Made of tool-grade steel with black-oxide protective coating.
Used twice, like new and very handy to have.
