I am having a hard time placing a new Huma Air pin probe into my FX Dynamic. The small round part on the end of the probe will not fit inside of the hole in the carrier....see photos.

I had the exact same problem if you measure the two with calipers you'll see Humas will not fit don't make the same mistake I did and try and file some material off it will not end up cylindrical and probe will not sit right I would contact Huma see what they say wish I had!

Im going back to stock....i tried sanding the huma probe a bit and once I finally was able to get it to go down, it was "crooked" after tightening the set/grub screw.

From what I understand there's not much benefit from a pin probe in this platform.
Slugs don't center very well in the factory mags and the pin probe can make loading not as smooth. I think they get cocked a little going into the chamber.
