Wanted to replace fiber on an older HHA single pin sight.Very flexible fiber, and much brighten than my aged fiber in my HHA sight. .019 fiber but melted the end a touch larger than the HHA was. Still able to see this fiber clearly at last legal light, was unable to see the original with 12min left to hunt.

Installs just like the standard fiber included with my Ultraview UV3XL target kit... Only... This fiber is a lot softer and easier to relax. The Ultraview fiber gets kinks in it, NOTHING you do will get it straight, your only option is to cut it shorter and shorter.Highly recommended - you're getting superior fiber for less money!

I had no expectations from ordering from this company because normally I order truglo or Shibuya for my fiber optics in my scopes. I was surprised to see how consistent and high quality the fiber was when I replaced my factory fiber on my B3 scope. I've ordered a .010 and a .019 and even the smaller size gave a bright dot when inserted into my scope where the default factory fiber was pretty dim. 100% would recommend.

First off the Hunter orange will look pink when you see it coiled up.The fiber is easy to work with and is very bright, I installed it on my Fast Eddie XL and I am very happy with the upgrade over the factory Orange

Perfect fit for my bow sight. Really bright optics, you can see it in the middle of the brightest days and it not overpowering at dusk and dawn. Very easy to install and seems to be durable

I used this fiber to replace the fiber in my Truglo Range Rover bow sight. I used all 40 inches. It may be to bright. Should be great for hunting and completes the problem I was having with the sight. Now I have a great sight I can use for years.
