Thread: Witness marks on RDS fasteners

  1. #1

    Witness marks on RDS fasteners

    I'm curious what people are using for witness marks/torque stripes on their RDS fasteners?

    I recently installed a pair of Holosun 407s, and I used a metallic silver color Sharpie I "borrowed" from my wife's craft supplies.

    The sharpie seems like a functional solution, but I was curious if a better option was available. I have no idea exactly how permanent the sharpie will prove to be, so I may need to re-witness at some point.

    I’ve had good luck with metallic sharpie on dots and archery equipment for several years now.

    Another +1 to the silver sharpie.

    I mark screws at 6 o’clock and I don’t mark the optic.

    I can black sharpie the screws and start over anytime.

    Sharpie oil-based paint markers for everything that needs a witness mark.

    I use the Sharpie fine tip paint markers or Testor paint markers… which ever I have laying around.

    What I’ve come to value more than the witness mark is a dab of E6000, not saying I don’t mark, but I’ve been very impressed with JCN’s suggestion on the product.

    You can use the edges of two pieces of masking tape to make a line, then fill in the line with the sharpie or paint pen. Boom. Clean and neat line

    I also use silver sharpie.

    Where does the E6000 come into play for optics mounting?

    A couple of places.

    I use some on mounting plates to slides to dampen vibration and take load off the plate screws.

    I use a little on the plate to optic recoil bosses to dampen vibration and take load off the optic screws.

    I use a little on the optic screws. Sometimes I use it instead of loctite.

    Usually I’ll put a little blue loctite on the tip of the screws and a dab of E6000 under the cap head.
