i have the predator...not sure bout the other sights..but i know my pins are all metal...unless something got inside the pin housing, they arent gunna break. they would have to be pulled or ripped out or something like that....

i had 4 .010 pins....i found that lowlight it was impossible to see them in certain areas shooting certain targets...were talkin almost dark....i went and had a .019 green pin thrown on top and boy what a world of difference. and still have me .019s for longer range stuff....love the setup...
