what is going on with this front sight? I have never seen a sight like that before. is it an aftermarket replacement for a 686 that had the front sight integrated into the barrel?

It is a factory target sight. Turn the horizontal wheel to select one of four front sight heights. Use an Allen wrench to adjust the individual settings for different bullet weights or speeds.

It was introduced by S&W to compete with the Python in PPC Distinguished Matches.

Distinguished matched did not allow a bull barrel and the M19 had a hard time keeping up with the Python with it's underluged barrel

S&W offered the adjustable front sight as an unfair advantage. The four clicks of the wheel are for the shooter to set their sights at 7,10,25 and 50 yards to hit the X-zone. Many shooters used a neck/head hold at 50 yards for more accurate sight picture...and set that adjustment for that amount of drop

If it is with-in the scope of the rule books, it is hard to claim it is an unfair advantage. S&W also used a different rifling twist in their 357 revolvers. Some claim it is more accurate with 38 Special ammunition, specifically 148 gr WC ammo. When I shot PPC, S&W ruled the trophy case.
