The original orange bar is so big and takes up so much sight picture that it is difficult to get a good aim with it. The TK unit is a smaller dot and the orange/green circle is much clearer to see inside the circle rear sight thus much better at aiming. This smaller dot does sacrifice some brightness compared to the factory unit but it is a much better tradeoff of accuracy for brightness. Some people might actually not like it being a big reduction in aim but if you are going for anything over 25 years it is a must have. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Excellent upgrade for the plastic blade *by F***T on Reviewed in the United States on March 12, 2014* The fiber optic rod (or "worm") is dependant on ambient light, so inside the Sub-2000's sight hood it's not terribly bright. Still, it's much easier to see than the original plastic blade was.Although pricey, it's cheaper and easier than other options that require replacing the entire sight assembly... ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars worth the upgrade . *by G***D on Reviewed in the United States on March 30, 2020* This sight upgrade is a good Move. the gun seems to be easier to get on target. However it should come with the metal lock / adjustment nuts. If you order do get the metal nuts with it. The plastic one broke just getting them out.Threading is a little tight but works fine. Work slow and very carefully. Lazier sighting tool Helps. --- ## 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.pl/products/5958790-tandemkross-sub-2000-su-16a-front-sight-upgrade](https://www.desertcart.pl/products/5958790-tandemkross-sub-2000-su-16a-front-sight-upgrade) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-09*
