I first tried searching the board for something on this -- I reely did -- but couldn't find what I needed.
I'm toying with the idea of replacing the factory fixed front sight with a railed gas block to accommodate a flip-up. Is this something considered user/owner do-able, or do I really need a good pro to get it right.
I have reasonable tool skills and a small shop including a drill press.
Thanks for any advice, either way.
