Tips for installing optics on pistols & rifles

When installing optics on pistols, rifles, etc. you want to know that your screws aren't loosening on you.

A paint pen of some kind has been used for a long time to give you a visual reference to see if the screws are still where you put them.

Torque your screws according to the manufacturers specifications then use a paint pen on the edge of the screw to mark alignment. #SelfDefence #Firearm #FirearmTraining #GunLicence #FirearmLicence
