help!! need advice for changing a rail

[CBlackjr]

I just got a new rail from omega and I got eveything on except that little part at the front of the rail. Its the part the sticks up inside the chamber and locks the barrel in place. I don't want to damage the little part so does any one have some good advice on how to get this peace out so i can drop it into my new rail. I know this thing should come strait up but its not going easily.

It is pressed in, so you will have to press it out!! If you are Careful , you can take it out with a small punch and hammer!! Otherwise, use a press, or a bench vise as a press!!
