I have them on my rifles. I use to have issues with the pins on my LMT SBR so I installed the KNS pins and !poof! no more issues. People are right in that 99.99% of the worlds shooters will never even realize the need for them. However for only $35 I just install them from the get go for insurance...........a just cuz item.
Besides I only put them on there for the same reason I put other shit on my rifles....CDI man, CDI!!![]()
