Hey guys,
I am into my first AR build and took apart my bcg for a quick cleanup and oiling, it has never been fired before.
Upon removing my extractor pin, the spring and O-ring stayed neatly in place but i did find a much smaller spring in the cavity. I cannot tell if it popped out of the middle of the spring/o-ring or if it was a small part that was just sitting there, a factory mistake maybe ?
Here is a pic for your expert opinions. I am done with my build...it kills me as it is the only thing remaining to figure out...

I do not have any brand name for the bcg, it is a 308 caliber.
Thanks !!
