I see guns with anti walking pins all the time and see them for sale everywhere, Is this a common occurrence? I have never had one walk out that I can remember. Now I might imagine some of those old M-16’s that has had numerous rounds through might do it. A couple of my older AR’s and My M-16 carbine has some rattle between the upper and lower from a ton of firing.
Thought maybe it’s a new thing but I have newer rifles that hasn’t done it, is these pins a legit thing or just more decorations. I guess they wouldn’t be a bad idea on a rifle that will be used hard.
