Ok, received my in the mail today too. Mine did the same as yours.

I have a Knight LRH which should have the same bolt set up as the extreme. However, the piece that fits on the end of the bolt (original Piece) slips on without effort.

When I went to slide the new piece in, it wedged about 1/2 way in. I had to use a small wooden mallet to get it to seat all the way into the bolt. Anyone know if that is how it is supposed to fit? Once it got it fully seated, the bolt slid into the gun and would lock down.

It will be a pretty major thing to remove it for cleaning as well.

I am also wondering it this is how it is supposed to be?
