cz 858 extra pin?

[mrq5daw]

I just got my cz858 and was replacing the grip and the guard rail but somehow I end up with an extra pin on the table where a worked, I am pretty sure it came from the rifle but I do not know where, I am thinking it was left inside there by accident in the factory but want to be sure before i go to the range..I checked all the pin but all is seems to be there..here is the pictures.

Did you take off your rear cover pin?
If so this is the part that keeps presure on your leaf spring by wedging against the rear cover pin.
Please refer to page 7, figure 2, part #26 in the following link;

yes.

Remove your dust cover and BCG. Pull the rear retaining pin out (all the way). Ensure that the leaf spring in the receiver is in the rear right corner aligned with the sidewall. Drop that pin into the hole running down through the retaining pin hole from the top. Depress the pin with a punch/nail/etc, and then reinsert the retaining pin. It should now be captive...
