Review: tienen muy buena calidad - tienen muy buena luminosidad Review: Good product, one color too dim - These seem like really and good, clear fiberoptics and I was happy overall with the product. Overall, they were flexible and strong and bright. My only complaint was the blue color was only about half of the brightness as all the rest of the colors. I installed in onto my 70 yard pin since will only be taking long shots in the day, but if I ever need it in the eve I don't know if I'll be able to count on it. ## Features - Bright - Fluorescent colors stand out against your target - Durable - Won't fade or over time - Flexible - Easily bends around sights and pins - Customize - Use colors you prefer on your sight - Standard sizes - Fits all bowsights and sight pins ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Nanoptics | | Color | Multi - Green, Yellow, Red, Blue and Hunter Orange | | Style | Modern | | Sport | Archery | | Item Weight | 0.05 Pounds | | Material | optical fiber | | Compatible Devices | Compatible with all devices | | Mounting Type | Bow Sight Mount | | Night vision | No | | Manufacturer | Nanoptics, Inc. | | Reticle Type | Single Pin | | UPC | 608729736127 | | Item Package Dimensions L x W x H | 7 x 2.6 x 0.4 inches | | Package Weight | 22.68 g | | Brand Name | Nanoptics | | Part Number | 029US-12P | | Size | 0.029" | ## Product Details - **Aiming Scope Sight Pin Size:** 0.03 inches - **Brand:** Nanoptics - **Color:** Multi - Green, Yellow, Red, Blue and Hunter Orange - **Compatible Devices:** Compatible with all devices - **Item Weight:** 22.68 g - **Material:** optical fiber - **Mounting Type:** Bow Sight Mount - **Sport:** Archery - **Style:** Modern - **Thread Type:** UNC ## Images !['Nanoptics Ultra Super Flex Replacement Bowsight Fiber 12'' (Pack of 5)' - Image 1](https://m.media-amazon.com/images/I/61YlG4s5NrL.jpg) ## Questions & Answers **Q: "Fits all bowsights and sight pins"? Really? Even when I have a sight pin that requires 0.050" fiber?** A: This description refers to all bowsight and sight pin styles, not the size. The pin size and fiber size should match. If you have a sight pin that is 0.050" - a unique size that is not standard in the industry - you would need an 0.050" fiber. **Q: will this fit my hi viz. front sight on my ruger mark iv** A: Your Hi Viz sight likely uses a much larger diameter than 0.029 which is the largest we offer on Amazon. Check with the sight manufacturer to compare sizes. **Q: Is this long enough for Trophy Ridge React 5 pin?** A: They're 12 inches, so they should be plenty long. I put them in my Trophy Ridge Hitman 7-pin with plenty of length to spare. Just make sure you get the right diameter. **Q: What size will I need for Springfield xdm .40** A: Springfield stock sights are 0.060". Unfortunately, we do not offer this size through Amazon. ## Customer Reviews ### ⭐⭐⭐⭐ tienen muy buena calidad *by A***Z on 22 January 2024* tienen muy buena luminosidad ### ⭐⭐⭐ Good product, one color too dim *by T***N on 10 July 2013* These seem like really and good, clear fiberoptics and I was happy overall with the product.
