how hard is it to drill a barrel for a fsp? what barrel contour do I need to do this?

Yes, I was referring to the L8A. I suppose "cut down" wasn't a very good choice of words.

It works as well as my old Colt factory carry handles, without the extra material that doesn't serve a purpose for me....except looking appropriate.

It's actually in stock directly from LMT right now. They're definitely not the easiest sight to find in stock.
