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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/40085755-ultra-super-flex-replacement-bowsight-fiber-12-pack-of-5](https://www.desertcart.sg/products/40085755-ultra-super-flex-replacement-bowsight-fiber-12-pack-of-5) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-31*
