I am at the point in my build where I am supposed to put the selector detent into the lower reciever.  My selector detent pin will not go into the selector detent hole.  The hole in the receiver is wider at the bottom and thinner at the top, I assume so it can catch the detent pin from going to far.  I'm trying to figure out if I have a defective pin or receiver.  Should the hole in the receiver be one diameter the whole way or is my pin a bit too large?

Nevermind...did a search and found my answer.

Thanks!
