Huh? I do send ins... almost every pin I do is made to fit a specific atty, even the ones that look like a standard screw. Most of the m3 pins are heavily modded as the heads are huge and very thick. M2.5 pins aren't usually modded as much but most of them require their heads to be shaved and polished.Is this where I can pick up a couple of m2.5 and m3 bottom feed pins?
