I haven't bought one yet, but I'm considering it. I currently have a 3 pin VBG trapper. I love the Trapper, but the ONE problem I have with it is that the inline pins obscure anything below your point of aim.

The triangle sight seems to eliminate that problem.

The only reasons I didn't buy it to go on my new Switchback is:
1. I wanted to see if they had an all green 3 pin version like they did with the trapper. Or maybe just green and amber. I don't care for red pins.
and
2. I was thinking I wanted to go with a 5 pin sight for a trip to B.C. for Caribou, but the 5 pin version of the triangle sight just seems too "busy" for me, if that makes any sense. I could probably do with only 4 pins really.
