These are a little of the weak side. I used a starter roll pin punch to get these going into an Aero lower. First hit with the hammer and these rollpins split right open. The wall isn't thick enough and the opening is ever so slightly bigger than some of my other rollpin that came from the big name manufacture down south.
Broke the last one by not installing it with the correct tools (Which I now have).||Works well, no issues with it.
