You shouldn't make fun of the "Tactical Witness Protection Program"!:big_boss:

Not every application lends its self to blue locktite. I do use it on scope mount screws but I also paint witness marks on them over kill guess so but wtf its just paint for witness marks :rolleyes: I don't use locktite on vltor off set light thumb screws because I don't want to clean them if I have to take the light off. My KAC handgaurd screw gets witness marks no locktite because it has a lock washer and it sits right next to the gas tube and blue locktite would just melt off and be a pain to clean.
Just take a really professional photo of your carbine under studio lighting after every time you shoot it, then post these photos on this site, and ask us to cross reference them for you. That should work... :)
Red sharpie paint pen works fine, if it comes off during cleaning just reapply.
Come one people, this is not rocket science here.
Go to the store, buy a paint marker in your favorite color, witness mark the screw, re-apply as necessary.
As mentioned above, in aviation we use Torque Seal or Paint Pens. Bright colors make visual inspection and identification of loosened hardware easy during pre-flight or servicing.

In this environment, “Torque Striping” can serve two purposes.
- First: Visual Inspection of Safety Of Flight items for looseness or vibration.
- Second: As a Quality Assurance tool during assembly to indicate that an item has been torqued and the installation “bought off” by QA personnel.
On weapons, I prefer to not have hardware that is “torque striped” like the tail rotor drive shaft coupling pictured above. In these cases I use a black paint pen, which doesn’t stick out to the extent a colored paint pen might, but still affords me the ability to inspect optic mount screws for vibration during routine mtx.
