5.5 mm Open-Ended Wrench for Front Sight Nut
$ 25
As a convenience, FFT offers a 5.5mm open-ended wrench for removal and installation of the front sight nut.
Most people will only need to remove and install this nut when adding the Meprolight Ghost Ring Tritium Inserts to their M1 or M4 shotgun.
Note: These are very well made, but all warranty claims must be made with the manufacturer - FFT does not guarantee or provide warranties for third-party tools.
