I have not personally used it. I have researched it alot, because I was looking to buy it last year. Im talking about the one that was new last year. they had a new version of it come out this year with only 2 pins, one fixed and one adjustable. The one i was looking at had 3 fixed and one adjustable.
from what i read, its a real solid sight. i havent read anything negative about it. solid construction, no broken pins, bright pins. people seem to really like the adjustable brightness on the light. over all, any review i read was good. the only down fall was the price, but everyone who commented on the high price also said they felt it was worth it, though it was a little high. i have found them new on ebay for about $130, thats about the cheapest I have seen. better than the MSRP $189 that many places still sell them for. im looking for a new sight this year, right now im leaning towards the new trophy ridge sights. i have used trophy ridge in the past and really like them. im still shopping though. good luck to you.
