now that's good info dave.

I actually contacted G5 and recommended they add the lock washers from the factory.

It's a cheap way to make sure that everything stays snug and G5 doesn't have to worry about guys like me breaking things.

On my bow I like blue lock tight items that will not be removed and plan on adding lock washers to things that I will adjust. Do I really need to do this to everything? Probably not. But they're preventative items that cost pennies now compared to hunting down a noise.

Since the installation of the lock washers the sight works perfectly. I also recommend the .019" pins

I can actually see the bullseye at 50+ yds and my groups have gotten smaller in the process.

I've shot outdoors in low light and haven't had to use the LED that comes with the sight.

Wow, this sight sounds awesome. I have been looking at them for some time now researching, but i think it's time to order one. I can't wait. Great Review.
