My old friend from long ago, Bill Wylde, made over 115 custom AR-15's, I think closer to 200. Widely recognized as the father of the accurate AR-15, one of his AR across the course guns would round out your number nicely too.
Bill was bored stiff with building across the course and varmint AR-15's so as a friend I couldn't ask him to build me one! I was able to put together an AR-15 top end myself that shot consistent 100 yard five shot five group aggregates in the low .2's from the bench and from the magazine. Still only a few hundred rounds or less shot through it but it is a safe queen belonging to my brother, NFS.
Bill liked building odd stuff and would send me pictures now and then. One day he sent me a picture of a four and a half inch group. It was a 600 yard, I believe ten shot group. The kicker is that Bill fired it with a ten inch barreled AR style pistol from the prone position!
I would like to have anything Bill ever built and any cue by the original Edwin Reyes. There is or was another Edwin Reyes from the Philippines building custom cues so that muddies the waters looking for a cue.
