Zero Dark Precision

Does anyone have any experience working with Zero Dark Precision? Im looking for a gunsmith to chamber and install a barrel as well as do some machining on my Remington 700 to turn it into a M40a3, just looking for a good gunsmith to do it and liked the fact that Zero Dark is local to me. Thanks in advance
 
I'll second the recommendation to ship it to LRI. I had a 700 bolt that needed timed and the handle welded. I had seen some of the work posted here by LRI of the exact job I needed done and it looked superb.

I opted to send it to another smith that had done some work for me in the past and boy was that ever a mistake. I could have done a better job on my own.

Just send it to LRI. When I need something done outside of my wheelhouse in the future, that's where it will go.
