The "new" white ones are a newer design. There is nothing wrong with the older style black ones. The "cup" side is supposed to contact the spring, under the failsafe arm.
If it was me, I would re-install it correctly, and load some ammo.
That is how it is installed now. I guess I just got used to seeing videos with the white one, it made me question the older style. As for loading some ammo, that just isn't happening yet. I am having to put this together little by little. So I bought the largest piece, now I have to get everything else. Tumbler, seperator, scale, etc. Thanks for the suggestion and help.
