Is there anyone that can do the olympic pistol caliber modification to a NON-OLY upper?  

I Picked up a .45 Cal A1 upper (FUN FUN FUN), and want to flat top it.  I have a flat top upper in the safe.  

Or would I just be better off and money ahead calling Olympic and getting a flat top pistol upper direct from them?

Thanks

What type of modification are you talking about? If you merely want to swap out uppers that is very different from milling off a charging handle and maching the upper receiver to accept a flat top rail. A gunsmith.

The olympic pistol upper has a couple of holes drilled in it for the ejector mod.  

Anyone?
