Description
Do you already own a Geissele Reaction Block, but have been eyeing the Green Jig? Keep your Geissele Tool and look no further.
This little piece of plastic slides over the pistol grip tang on your AR15 Lower. When used with the Geissele Reaction Block, you grab both the Reaction Block and this Plastic Jig in your vise at the same time.
This jig insures 100% Buffer Tube to Lower Receiver Alignment.
