Need Help With Bushnell First Strike

[Stryker]

Hey Everybody.  I have a 2012 First Strike red dot sight that I'm trying to mount on my S&W - M&P 15.  The small metal piece that secures the sight to the rail became stripped.  Can anyone tell me where to find a piece like this.  The photo below should give you an idea of what I'm talking about.  Thanks in advance.

I've got two, but that's not an "optional" part, otherwise I'd send it to you. 

Guess you're going to find out how good Bushnell customer service is.

Already did.  And it's actually really good.  They have the part in stock and are shipping it to me.  Should be here in a few days.  And it only cost me a few dollars.
